Participants

Reaction Steps

To 3-[2-(4-Amino-1-piperidyl)ethyl]indole (1.307 g.) suspended in a solution of triethylamine (2 mls.) in dichloromethane (10 mls.) at room temperature with stirring was added methane sulphonyl chloride (0.570 g.) in dichloromethane (5 mls.). After stirring for 18 hours the solution was washed with water and the organic phase separated, dried and evaporated to yield the title compound (1.690 g.) as an oil. This was recrystallized from ethanolic hydrogen chloride as the hydrochloride salt (0.560 g., m.p. 241°-242° C.).
