실험 절차

A mixture of 2.5 g. of methyl-6-chloro-1,2,3,4-tetrahydrocarbazole-2-carboxylate, 20 g. of liquid ammonia and 150 ml. of methanol was placed in a pressure bottle. The mixture was shaken at 60° for 40 hours (internal pressure 60 lb/in2). Upon cooling to room temperature, the mixture was concentrated to dryness yielding 2.1 g. of product. Following a crystallization from ethyl acetate, 0.8 g. of 6-chloro-1,2,3,4-tetrahydrocarbazole-2-carboxylic acid amide was obtained, m.p. 203°-204°.
