A solution of 328.0 mg (1.5 mmol) of 4-chloro-8-methoxy -3-quinolinecarbonitrile, 309.7 mg (1.8 mmol) of 3-bromoaniline and 173.3 mg (1.5 mmol) of pyridine hydrochloride in 15 ml of 2-ethoxyethanol was refluxed under nitrogen for 0.5 hours. The solvent was removed and the residue was diluted with water followed by neutralization to pH 7-8 with diluted sodium carbonate solution. The precipitate was collected and washed with ether and dried in vacuo to give 476.1 mg (89.6%) of the product as a yellow solid, m.p. 210-212° C.; mass spectrum (electrospray, m/e): M+H 353.8, 355.8.
