Reaction Steps

3-Cyanomethyl-1H-indol-1-amine (12 g) and 4-chloropyridine hydrochloride (12 g) were combined in isopropanol (250 ml). After stirring at reflux (90° C.) for six hours, the mixture was poured into water (500 ml) and stirred five minutes. Thereafter the pH of the mixture was adjusted to 10 with sodium carbonate and the mixture was extracted with ethyl acetate (2x). The organic layer was washed with water (2x), brine, dried over anhydrous magnesium sulfate, filtered and evaporated to give an oil (22 g). This oil was eluted on a silica gel column with ethyl acetate. Fractions containing product were combined and concentrated to an oil (16 g) which solidified upon standing. A portion of this solid was recrystallized from ethanol/ether (1:20) to give the title compound as a solid (2 g), m.p. 152°-153° C.
