Reaction Steps

The title compound was prepared by the same procedure for preparing 1-pyridin-3-yl-ethylamine from 1-(1-methyl-1H-indol-4-yl)-ethanone (1.75 g, 10 mmol), 2 M ammonia solution in methyl alcohol (25 mL, 50 mmol, Aldrich), acetic acid (15 mL, J. T. Baker) and sodium cyanoborohydride (2.5 g, 40 mmol, Aldrich). The title compound was purified by column chromatography (silica gel, 2 M ammonia solution in methyl alcohol/ethyl acetate 1/10) in form as light yellow oil in 48% yield (0.83 g, 4.8 mmol).
