Reaction Steps

A mixture of 0.090 g of 4-chloro-6-methoxy-7-(3-pyridin-4-yl-propoxy)-quinoline-3-carbonitrile, 0.050 g of 3-hydroxy-4-methylaniline, 0.039 g of pyridine hydrochloride and 3 ml of ethoxyethanol was stirred under nitrogen at reflux temperature for 20 minutes. The mixture was cooled and filtered. The product was washed with saturated sodium bicarbonate, water, then dried to give 0.080 g of 4-(3-hydroxy-4-methyl-phenylamino)-6-methoxy-7-(3-pyridin-4-yl-propoxy)-quinoline-3-carbonitrile hydrochloride as a solid, dec >153° C. ; mass spectrum (electrospray, m/e): M+H 440.9.
