Procedure

To 10.0 g (38.4 mmol) 4-chloro-6-cyanoquinoline-3-carboxylic acid ethyl ester was added 10.4 g (50 mmol, 1.5 eq) 3-chloro-4-methoxybenzyl amine hydrochloride and 35 mL (228 mmol, 6 eq) diisopropylethylamine (Aldrich, 99.5+%). The mixture was dispersed in 200 mL n-propanol and brought to reflux for two hours. The solution was then poured into 500 mL water. The resulting precipitate was filtered, then washed with 500 mL water, then twice washed with 50 mL absolute ethanol to yield 14.87 g (37.6 mmol, 97% yield) of the title compound as a white fiberous solid after codistilling with absolute ethanol: mp: 161-162° C.; LC/MS (M/Z) 396 [M+H] observed, 97% purity.
