To a solution of 0.152 g (1.89 mmol) of formamidine hydrochloride in 10 ml of methanol under argon is added 0.102 g (1.89 mmol) of sodium methoxide. After stirring 5 min., a solution of 0.46 g (1.26 mmol) of 4-[(dimethylamino)methylene]-1,2,3,4-tetrahydro-1-(4-nitrobenzoyl)-5H-1-benzazepine-5-one in 5 ml of methanol is added and the mixture stirred 18 hours. The solvent is removed, dichloromethane added, and the mixture filtered. The solid is washed with dichloromethane. The combined filtrate is concentrated to dryness to give 0.47 g of tan foam. The preceding solid is purified by chromatography on silica gel. The compound is dissolved in ethyl acetate-dichloromethane and applied to the column. The column is then eluted with ethyl acetate to give 0.25 g of product as pale yellow crystals.
