Participants

Reaction Steps

A solution of 3-chloro-8-methoxy-2,3,4,5-tetrahydro-1H-[1]-benzazepin-2-one (12.5 g) and sodium azide (4.3 g) in dimethylsulfoxide (150 ml) was maintained at 80° under an atmosphere of nitrogen for 3 hours. The reaction mixture was poured into ice/water (300 ml) and the suspension was stirred for 30 minutes. The solid was filtered off, washed with water (50 ml) and dried to give 3-azido-8-methoxy-2,3,4,5-tetrahydro-1H-[1]-benzazepin-2-one, m.p. 136°-138°.
