Procedure
Aluminum chloride (30.8 g, 231 mmol) was added to a solution of 1-acetyl-2,3,4,5-tetrahydro-1H-1-benzazepine (17.5 g, 92.5 mmol) and 3-chloropropionyl chloride (13.2 ml, 139 mmol) in dichloroethane under cooling with water-bath, and then the mixture was stirred at 50° C. for 1 day. The reaction solution was poured into iced water and extracted with dichloromethane. The extract was washed with a saturated saline solution and dried over anhydrous sodium sulfate, and the solvent was distilled away under reduced pressure. The resultant residues were purified by silica gel column chromatography (developing solvent; hexane:ethyl acetate=1:1) and crystallized from hexane, whereby the title compound (8.47 g) was obtained as colorless powder with a mp. of 106 to 107° C.
