Procedure

In one portion, 11.5 mL (49 mmol) of a 4.34M methanol solution of sodium methoxide was added to a solution of 11.0 g (31 mmol) of a mixture of 8-chloro-1-phenyl-5H-2-benzazepine-5-carboxylic acid butyl ester and 8-chloro-1-phenyl-3H-2-benzazepine-5-carboxylic acid butyl ester and 5.7 g (60 mmol) of acetamidine hydrochloride in 200 mL of ethanol. The mixture was refluxed for 18 hr, cooled and poured into 800 mL of water. The resulting precipitate was collected by filtration and washed with ether to yield a yellow solid. Recrystallization from tetrahydrofuran gave off-white prisms, mp 155°-160°.
