Sulfur analogs of psychotomimetic amines.

The syntheses and physical properties are described for 2,5-dimethoxy-4-methylthiophenylethylamine and 2,5-dimethoxy-4-methylthiophenylisopropylamine. The latter compound is the sulfur analog of the psychotomimetic phenylisopropylamines 2,4,5-trimethoxyphenylisopropylamine and 2,5-dimethoxy-4-methylphenylisopropylamine wherein the methylthio group replaces a methoxy group or a methyl group, respectively. This compound is predicted to be about 30 times as active as mescaline.
