Versuchsvorschrift

Aluminum chloride (17 g, 130 mmol) was added by portions to a solution of 3-(trifluoroacetyl)-2,3,4,5-tetrahydro-1H-3-benzazepine (15.0 g) and 5-chlorovaleryl chloride (8.8 ml) in 1,2-dichloroethane (40 ml) under ice-cooling. After stirring at room temperature for 30 minutes, the reaction mixture was poured into ice (500 g), extracted with ethyl acetate, and washed with brine. The organic layer was dried over anhydrous magnesium sulfate, the solvent was evaporated under reduced pressure, and the residue was crystallized from ethanol-diethyl ether to give a pale yellow solid (15.2 g). Further recrystallization from ethanol-diethylether afforded colorless crystals (13.2 g) as the title compound.
