Versuchsvorschrift
A mixture of 0.248 g (1 mmol)of 4-chloro-6,7-dimethoxy-quinoline-3-carbonitrile, 0.151 g (1.1 mmol) of 3-amino-2-methylbenzyl alcohol, 0.116 g (1 mmol) pyridine hydrochloride and 12 ml of 2-ethoxyethanol was heated in a 138-140° C. oil bath for 6 hours; progress of the reaction was monitored by TLC. When TLC indicated the disappearance of starting material, the reaction was cooled and concentrated in vacuo to a thick oil. To this oil was added 50 ml of water followed by 5 ml of 1M NaHCO3, approximately pH 8. The resulting precipitate was collected, washed with water and diethyl ether, and dried in vacuo at 65° C. to give 0.32 g (91.5%) of the desired product as light tan crystals. MP 123-125° C.; : mass spectrum (electrospray, m/e,): 349.9(M+H)+.
