Procedure

A mixture of 500 mg (1.34 mmol) 4-[(4-chloro-2-fluorophenyl)amino]-7-methoxy-6-nitro-3-quinolinecarbonitrile, 20 ml ethanol and 1.52 ml (6.71 mmol) tin chloride dihydrate was heated to reflux under N2. At 3 hours, removed heat, added ice water and made basic with sodium bicarbonate. Stirred for several hours and extracted with chloroform. Dried organic layer with sodium sulfate, stripped solvent and dried in vacuo, giving 350 mg of green solid: mass spectrum (electrospray m/e): M+H=342.9, 344.8.
