Procedure

To a solution of methyl 2,3,4,5-tetrahydro-8-methoxy-2-oxo-1H-1-benzazepine-4-carboxylate (5.035 g) in methanol (60 ml) was added 1 N aqueous sodium hydroxide (40 ml). The reaction mixture was stirred at room temperature for 6.5 hr, made acidic by adding 1 N aqueous hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with water and saturated aqueous sodium chloride, dried, and concentrated. The resulting crude crystals were washed with diethyl ether to obtain the titled compound (4.253 g).
