Reaction Steps

Aluminum chloride (23.5 g, 176 mmol) was added to a solution of ethyl 3,4-dihydro-1(2H)-quinoline carboxylate (14.5 g, 70.4 mmol) and 3-chloropropionyl chloride (7.39 ml, 77.4 mmol) in dichloromethane under cooling with water-bath, and the mixture was stirred at room temperature for 14 hours. 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 resulting residues were purified by silica gel column chromatography (developing solvent; hexane:ethyl acetate=3:1) and crystallized from hexane, whereby the title compound (15.6 g) was obtained as colorless powder with a mp. of 78 to 79° C.
