Методика

A mixture of 5.00 g (21.5 mmol) 4-chloro-6-nitro-3-quinolinecarbonitrile, 250 ml ethanol, and 6.18 g (25.8 mmol) 3-chloro-4-(1-methyl-1H-imidazol-2-ylsulfanyl)-aniline (WO-9615118) was heated to reflux under N2. Removed heat at 3½ hours and made basic with a solution of saturated sodium bicarbonate. Stripped solvents and azeotroped with ethanol. Slurried residue with hexane and collected solids. Washed with water, dried in vacuo. Boiled solids in hexane to remove excess aniline, air dried. Boiled in 2 L ethyl acetate, and because of extreme insolubility, collected solids and dried in vacuo, giving 5.90 g of yellow solid: mass spectrum (electrospray m/e): M+H=437.2, 439.1.
