p-Toluenesulfonic acid → HCID 22165466, compound

Participants

Reaction Steps

16.2 g of acrylamide and 0.9 g of anhydrous p-toluenesulphonic acid were added to 30.6 g of 1-(6,8-dichloro3,4-dihydro-2(1H)-naphthyl)pyrrolidine. The mixture was heated under nitrogen to 100° for 2 hours and to 150° for 2 hours. After cooling, the reaction mixture was stirred at room temperature in 80 ml of a mixture of chloroform-ethyl acetate (1:1). There was obtained 8,10-dichloro-1,4,5,6-tetrahydrobenzo[f]quinolin-3(2H)-one which melts at 212°-214° after recrystallization from ethyl acetate.
