Procedure

A mixture of 6.70 g (16.1 mmol) 4-[(3-iodophenyl)amino]-6-nitro-3-quinolinecarbonitrile, 300 ml ethanol, and 18.2 g (80.5 mmol) SnCl2 dihydrate was heated to reflux under N2. Removed heat at 2 hours, added ice water. Added sodium bicarbonate until pH was basic, forming a thick yellow mixture. Stirred for 2.5 hours. Extracted with chloroform, stirred organic portion with Darco and filtered through magnesium sulfate. Stripped solvent and dried in vacuo, giving 3.48 g of yellow-brown solid: mass spectrum (electrospray m/e): M+H=387.0.
