실험 절차

A mixture of 0.12 g (0.52 mmol) of 8-chloroimidazo[4,5-g]quinoline-7-carbonitrile, 0.2 g (0.63 mmol) of 2-bromo-4-chloro-5-methoxyaniline hydrobromide and 0.06 g (0.52 mmol) of pyridine hydrochloride in 5.0 mL of 2-ethoxyethanol is heated at reflux temperature for 1 hour, cooled to room temperature, poured into a saturated solution of sodium bicarbonate and stirred for 0.5 hour. The solid is collected by filtration, washed with water and dried. The solid is purified by silica gel chromatography utilizing a gradient of methylene chloride/methanol(97:3 to 90:10) to yield 0.1 g of 8-(2-bromo-4-chloro-5-methoxy-phenylamino)imidazo[4,5-g]quinoline-7-carbonitrile as a yellow solid, mp 257° C. (dec).
