A mixture of 3.10 g (8.40 mmol) 4-[(4-bromophenyl)amino]-6-nitro-3-quinolinecarbonitrile, 155 ml ethanol, and 9.47 g (42.0 mmol) SnCl2 dihydrate was heated to reflux under N2. After 4 hours, removed heat and added ice water. Made basic with sodium bicarbonate and stirred for 2 hours. With mixture still basic, extracted with chloroform, stirred organic layer with Darco and dried with sodium sulfate. Filtered, stripped solvent and dried in vacuo, giving 2.265 g of brown-yellow solid: mass spectrum (electrospray m/e): M+H=339.0, 341.0.
