Reaction Steps

A solution of 9-chloro-2,3,4,5-tetrahydro-3-methyl-1H-3-benzazepin-6-amine (633 mg, 3 mmol) in acetic acid (6 ml) was treated with 2,5-dimethoxytetrahydrofuran (396 mg, 3 mmol) and stirred at 110° C. for 1.5 hours. The mixture was poured into ice, basified with 10% sodium hydroxide and extracted with ethyl acetate. The organic phase was dried, concentrated and treated with hydrogen chloride to give 6-chloro-2,3,4,5-tetrahydro-3-methyl-9-(1H-pyrrol-1-yl)-1H-3-benzazepine hydrochloride (methanol-acetonitrile); mp 262°-264° C.
