Potassium Carbonate → 4-(3-Bromophenylmethylamino)-6,7-diethoxy-3-quinolinecarbonitrile

Participants

Reaction Steps

A stirred mixture of 4-chloro-6,7-diethoxy-3-quinolinecarbonitrile (0.69 g, 2.5 mmol), 3-bromobenzylamine (0.78 g, 3.5 mmol), diisopropylethyl amine (1.05 ml, 6.0 mmol), and 7.5 ml of ethoxyethanol was refluxed for 4 h, cooled, and stirred with a mixture of hexane and water containing 0.4 g of potassium carbonate for 3 h. The resulting solid was filtered, washed with water, and dried. Recrystallization from acetone-hexane gave 0.73 g of off-white solid, mp 156-159° C.
