Procedure
1.00 g of ethyl p-[(2,3,4,5-tetrahydro-1,5,5-trimethyl-2-oxo-1H-1-benzazepin-7-yl)carbamoyl]benzoate in 75 ml of ethanol/water (2:1) was treated with 0.40 g of sodium hydroxide and the reaction mixture was stirred at room temperature overnight. Thereafter, it was poured on to ice/conc. hydrochloric acid, extracted with ethyl acetate, the extract was washed with saturated sodium chloride solution, dried and concentrated up to crystallization. There was obtained 0.79 g of p-[(2,3,4,5-tetra- hydro-1,5,5-trimethyl-2-oxo-1H-1-benzazepin-7-yl)carbamoyl]benzoic acid, m.p. >275° C.
