Reaction Steps

1-(2-Chloroethyl)pyrrolidine hydrochloride (1.27 g, 7.5 mmol) was added to 7-hydroxy-6-methoxy-4-phenoxyquinazoline (1.0 g, 3.7 mmol), and potassium carbonate (3.9 g, 28.3 mmol) in DMF (30 ml). The mixture was heated at 110° C. for 4 hours and allowed to cool. The mixture was filtered, and the volatiles were removed from the filtrate by evaporation. The residue was purified by column chromatography eluting with methylene chloride/methanol/ammonia, (100/8/1) to give an oil which was triturated with ethyl acetate to give 6-methoxy-4-phenoxy-7-(2-(pyrrolidin-1-yl)ethoxy)quinazoline (200 mg, 15%) as a white solid.
