実験手順

Freshly distilled benzaldehyde (2.96 g) was added to a solution of 3-(2-aminoethyl)-1H-indole-5-carbonitrile (5 g) in absolute ethanol (120 ml). The mixture was heated at reflux for 2 h before cooling to 10°. Sodium borohydride (1 g) was added and the suspension stirred for 2 h. The mixture was reduced to dryness and the residue recrystallised from a mixture of toluene and petroleum ether (b.p. 60°-80°). The solid was washed well with water and dried to give the title compound as a powder (3.8 g), m.p 99°-101°.
