Reaction Steps

38.5 ml of a 0.17 M solution of ethyl 4-chloroquinoline-3-carboxylate in xylene, and 0.96 g of p-cyanophenylhydrazine in 30 ml of xylene are mixed and heated at 115° to 120° for 3 hours. The mixture is then cooled to room temperature, and stirred with 20 ml of 1 N aqueous sodium hydroxide and sufficient water to dissolve all solids. The aqueous layer is separated, washed twice with diethyl ether, then treated with an aqueous solution of 1.07 g ammonium chloride, and the resulting precipitate is collected, washed with water and dried to yield the 2-(p-cyanophenyl)-pyrazolo[4,3-c]quinolin-3(5H)-one, showing peaks in the IR-spectrum at 885, 830, 780, 755 and 730 cm-1.
