Reaction Steps

A mixture of 5.017 g (19.0 mmol) 4-chloro-7-methoxy-6-nitro-3-quinolinecarbonitrile, 250 ml ethanol, and 2.55 ml 22.8 mmol) 4-chloro-2-fluoroaniline was heated to reflux under N2. At 3.5 hours, removed heat and made basic with saturated sodium bicarbonate. Stripped solvents and azeotroped with ethanol. Slurried residue with hexane, collected solids, and washed with water. Dissolved in ethyl acetate, stirred with Darco, filtered, stripped solvent, and dried in vacuo, giving 6.54 g of yellow solid: mass spectrum (electrospray m/e): M+H=372.8, 374.8.
