Procedure: Diethyl azodicarboxylate (209 mg, 1 mmol) was added dropwise to a mixture of 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (128 mg, 0.4 mmol), (prepared as described for the starting material in Example 2), cis-3-(2,6-dimethylmorpholino)-1-propanol (97 mg, 0.56 mmol) and triphenylphosphine (314 mg, 1.2 mmol) in methylene chloride (4 ml) under nitrogen. The mixture was stirred for 1 hour at ambient temperature and the solvent was removed by evaporation. The residue was purified by column chromatography eluting with methylene chloride/methanol (95/5 followed by 90/10). The purified product was dissolved in methylene chloride and 2M ethereal hydrogen chloride (1 ml) was added. The solution was diluted with ether and left to stand. The resulting precipitate was collected by filtration, washed with ether and dried under vacuum to give 4-(4-chloro-2-fluoroanilino)-7-(3-(2,6dimethylmorpholino)propoxy)-6-methoxyquinazoline hydrochloride (130 mg, 590%).
