Procedure

A mixture of 6.753 g (15.6 mmol) 4-[(3-chloro-4thiophenoxyphenyl)amino]-6-nitro-3-quinolinecarbonitrile, 250 ml ethanol, and 17.66 g (78.0 mmol) SnCl2 dihydrate was heated to reflux under N2. Removed heat at 2 hours, added large volume of ice water, and made basic with sodium bicarbonate. Stirred for 2 hours and with mixture still basic, extracted with chloroform. Stirred organic layer with Darco, dried with sodium sulfate, filtered, stripped solvent and dried in vacuo, giving 5.996 g of yellow-brown solid: mass spectrum (electrospray m/e): M+H=403.1, 405.1.
