What to do with tryptamine?
I have a large amount of pure tryptophan and recently came across an exceedingly simple method of making it into tryptamine: basically just reflux it
a mixture of xylene and acetone until CO2 stops evolving. A spearmint oil catalyst can be used to speed the reaction but adds a purification step
afterward and reduces yield.
My question is: what can I do with the resulting tryptamine? There are a whole slew of interesting substances that are related to tryptamine, but there's very little information on synthesizing those substances using tryptamine as a starting
material. Are there any easy ways to do this?
Of particular interest to me are AMT (an MAOI), serotonin (neurotransmitter), and DMT (which is an interesting precursor to other syntheses). The
molecular changes aren't complicated; there just isn't a lot of experimental info out there.

Decarboxylate and post a write up with the procedure, yield, and product identification ( melting point, solubility's, etc) before even worrying about
methylation.

Wow, if you really made it, it is a good news! You can make DMT (if it's legal in your country) or DIPrT - this is known to cause auditory
hallucinations only.

Very interesting. Have you successfully thermally decarboxylated tryptophan? Tryptamines fascinate me. I'm going to read TIHKAL one of these days, I
hear Shulgin did a serious amount of research on tryptamines.

Doubtful, he mostly obtains his typtamines using other starting materials or hard to get reagents. Google is your friend here.

Actually Shulgin was eager to develop routes from uncontrollable materials and you will find that he published a route for most of his not ring
substituted tryptamines starting with tryptamine or at least gave an outline. Shulgin is a good, humble guy who lets his actions speak.
What he missed was the sodium triacetoxy borohydride (made in-situ) reductive methylation of tryptamine with formaldehyde to DMT. I have heard a few
success reports. Yields are low in an amateur setting, but given that it's only two steps from (dirt cheap) tryptophan, overall yield is better than
for most OTC routes to phenethylamines.

Isn't it possible to methylate tryptamine using simply H2SO4 + methanol?

Maybe it's not possible in theory, but in practice it is.

A lot of triptan drugs are methylated by reductive alkylations. I think this is a conditions thing. But yes...pictet-spengler can be a competing
reaction.
Edit: haha originally unintelligible.

Thing is, formation of an intermediate imine/iminium cation should react much faster intramolecularly than intermolecularly, although I agree perhaps
there are conditions where the Pictet-Spengler cannot occur. I suspect if you can use conditions which would adversely affect the breaking of
aromaticity in the intramolecular attack then it may be possible. Perhaps thats why typical Eschweiler-Clarke conditions cannot be employed, as I am
sure that reaction proceeds via the P-S pathway.

I was just looking up naturally occuring tryptamines and came across this one:
Norbaeocystin
its psilocybin without the N-methyl groups. The wiki page doesn't say much about it but the wiki page for its mono-N-methylated analogue, baeocystin,
states that:
| Quote: |
Little information exists with regard to human pharmacology, but in the book Magic Mushrooms Around the World, author Jochen Gartz reports being aware
of a study in which "10 mg of baeocystin were found to be about as psychoactive as a similar amount of psilocybin." |
Heres another interesting one:
5-Bromo-DMT
According to the wiki page, it occurs naturally in some marine invertebrates. I read that in animal studies, there were indications that it had
sedative and antidepressant properties. This molecule caught my interest because I remember, in a documentary about LSD, hearing about bromo-LSD which
has no psychoactive properties but happens to cure cluster headaches.
Heres a strange one:
Convolutindole A
It also occurs in some marine invertebrates. According to the wiki page, it is an effective anti-nematode (parasitic worm) drug.

Melatonin powder is pretty easy to find too, making all 5-MeO tryptamines available easily. Assymetrically substituted 5-MeO tryptamines should be
easy from melatonin too.

Really? I heard only of one success report wich was with comercial triacetoxyborohydride and I think a fake as triacetoxy borohydride
is extremly sensetive to water and aqueous formaldehyde was used. NaBH(CH3COO)3 or NaBH4/CH3COOH are also able to reduce the indole (see for example
"NaBH4 in carboxylic acid media" on Rhodium archive)! You will get a product but I guess no dialkytryptamines.
Can u link any success reports?
Cold alkaline aquesous NaBH4 solution and aq. formaldehyde should work for formylation by simultaneuos titration (and large excess) into an ice cold
alcoholic solution of the substrate. Or build imine first before adding NaBH4.
A little cross quoting about reductive alkylation:
| Quote: |
Eschweiler-Clarke does not work at all. Picted-Spengler would be the main-reaction.
Also Al/Hg does not work very well/ ~20% yields. Source: Tihkal
NaBH(CH3COO)3 or NaBH4/CH3COOH does also not work/leads to extremly low yields or needs special conditions, because it does reduce indole. Source:
Rhodium archive - several documents on triacetoxyborohydride and NabH4 in carboxylic acid media are mentioning reduction of indoles with it and some
derivates.There are some other reciepes on the in the internet, where this is used to make DMT from tryptamine and aq. Formaldehyde. I think it's pure
a fake. Triacetoxyborohydride is very sensitive to water and does reduce indole - no big chance to work under the mentioned conditions (RT, THF,
excess CH3COOH as solvent).
BH3*THF or NaBH4/H2SO4 or NaBH4/I2 does also not work. The indole gets also reduced very fast under normal conditions.
NaBH4/MeOH . Does work (!!!), but does reduce aldehydes faster than imines/enamines form. It has to be very cold and a large excess of NaBH4 and
aldehyde are neccessary. Does work better for diethylated than for dimethylated tryptamines Source: The Vespiary
H2+Pd/C. Does also work. But needs high pressure of H2. Does sometimes overdo it's job when the catalyst is too strong. Source: Tihkal
Sodium cyaboborohydride does work well but produces side products, esp. beta carbolines. Good workup necessary. Source: Rhodium archive/Vespiary
Untested but very interesting: Zinc borohydride, potassium borohydride and Zn/NaH2PO4
Zinc borohydride because it's known to perfom very well for dialkylations of amines, potassium borohydride because it less active and smoother than
NaBH4 and Zn/NaH2PO4 because it's known to alkylate amino acids and alkylamines in high yields. Zn/NaH2PO4 and formaldehyde does also work for
dialkylation of tryptophane.... but dimethyltryptophane is very hard to get ripped of CO2 and is extremely toxic. Try it yourself.

I've seen the analytical data and it's unambigous. Though isolated yield was low (~1 g DMT from 5 g tryptamine).
| Quote: | | NaBH(CH3COO)3 or NaBH4/CH3COOH are also able to reduce the indole (see for example "NaBH4 in carboxylic acid media" on Rhodium archive)!

See Chem. Soc. Rev.,27,395(1998).

Do an old school DMT synthesis and grow the cool looking crystals DMT forms. Don't vaporize them because its neurotoxic to your 5ht2a and you need
those.

From last I heard, the "spearmint" method of decarboxylation was fake (the "Student").
I attempted myself very crudely with a sticky, nasty mess. My skills by no means constitute incapability of the reaction. However I do believe that a
molar ratio of spearmint oil (or molar equivalent of acetophenone) will fully decarboxylate the product... Whether the pictet-spengler occurs, I am
again not sure.
I may continue reading up on this in the future.
I'll report anything.
==Making ethyl bromide is quite easy.
==Obtaining diisopropylethylamine is tricky - but some people can get it.
Tryptophan -> DET may be an easy route for a hobbyist.

I don't believe the OP asked anything about ingestion of tryptamine or its methylated variants. I do hope that the original poster has read these
threads on decarboxylation of tryptophan right here on SciMad. I also saw some patents on the subject IIRC.

yes
Edit: On second thought I feel like I should explain the theory ive formed after researching DMT. DMT is a naturally occurring chemical in the brain
as well as plants and possibly other places. It is released during life or death situations or near death experiences and has been thought to be the
cause of people hallucinating when they die but are resuscitated. It may exist as natures way of saying you need to not let that happen again because
it is not a pleasant experience for most people. However.. It's said to produce some euphoria by agonizing 5ht2b receptors and is considered
neurotoxic to these receptors along with others. Its associated with the "I'm going to die" state of mind.

On a similar note, what can be done with phenylethylamine? You can buy tons of pure PEA hydrochloride from some supplement website. Nothing naughty of
