Versuchsvorschrift

A mixture of 5.734 g (13.1 mmol) 4-[3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)-phenylamino]-6-nitro-quinoline-3-carbonitrile, 250 ml ethanol, and 14.83 g (65.6 mmol) tin chloride dihydrate was heated to reflux under N2. Removed heat at 2½ hours and added a large volume of ice water. Made basic with sodium bicarbonate and stirred for 2 hours. With mixture still basic, extracted with chloroform, stirred organic layer with Darco, dried with sodium sulfate and filtered. Stripped solvent and dried in vacuo, giving 2.86 g of yellow-brown solid: mass spectrum (electrospray m/e): M+H=407.3, 409.3.
