Procedure
A suspension of 3-azido-1-ethoxycarbonylmethyl-8-methoxy-2,3,4,5-tetrahydro-1H-[1]-benzazepin-2-one (13.8 g) in methanol (75 ml) was treated with a solution of sodium hydroxide (1.9 g) in water (75 ml). The reaction mixture was stirred at 40°-45° for 2 hours. Water (100 ml) was added and the mixture was acidified with concentrated hydrochloric acid (10 ml) and extracted with methylene chloride (3×75 ml). The combined methylene chloride solutions were dried over magnesium sulfate and evaporated at reduced pressure to give 3-azido-1-carboxymethyl-8-methoxy-2,3,4,5-tetrahydro-1H-[1]-benzazepin-2-one, m.p. 145°-147°.
