For example, the pA2 values for 1-(4-methoxyphenyl)-2-aminopropanol, 5.22 +/- 0.12, n = 3, and 1-(4-methylphenyl)-2-aminopropanol, 5.40 +/- 0.18, n =
4, do not differ subtantially from those of 10(1-(4-methoxyphenyl)-2-aminopropane, 5.15, +/- 0.04, n =
5) and 14(1-(4-methylphenyl)-2-aminopropane, 5.51, +/- 0.11, n = 2), while the
pA2 value for 1-(4-methoxyphenyl)-2-aminopropanol (43a), 4.90 +/- 0.10, n = 3, is considerably lower than the pA2 of the
corresponding 2,4-dimethoxyphenylisopropylamine (16)(5.60, +/- 0.08, n = 4).
