A mixture of 4.17 g (0.0149 moles) of the N-(4-chloro-3-cyano-7-ethoxy-6-quinolinyl)acetamide, 4.04 g (0.0173 moles) of 4-benzyloxy-3-chloro-phenylamine (example 5), and 2.0 g (0.017 moles) of pyridine hydrochloride in 85 ml of isopropanol was stirred and refluxed in an oil bath for 30 minutes. The reaction was cooled in an ice bath, and the solid was collected by filtration and washed with isopropanol, and then with ether yielding 7.26 g of crude product as the hydrochloride salt. This material was purified by chromatography of the free base on silica gel by elution with 1:39 methanol-methylene chloride.
