Participants

Reaction Steps

A mixture of 0.4 g (1.05 mmol) of 8-chloro-6-phenyl-3H,4H-pyrazolo[3,4-d][2]benzazepine-3-acetic acid ethyl ester and 20 ml of methanolic ammonia (ca 20% v/v) was heated in an autoclave on the steam bath overnight. The solvent was evaporated and the residue was purified by chromatography over 15 g of silica gel using 5% (v/v) of ethanol in methylene chloride. Crystallization from ethyl acetate/ether gave colorless crystals with mp 218°-219°.
