実験手順

Diethyl azodicarboxylate (295 μl, 1.8 mmol) was added dropwise to a solution of 1-(3-hydroxypropyl)imidazole (102 mg, 0.81 mmol), (EP 0060696 A1), 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (200 mg, 0.62 mmol), (prepared as described for the starting material in Example 24), and triphenylphosphine (492 mg, 1.8 mmol) in methylene chloride (4 ml) and the mixture stirred for 2 hours at ambient temperature. The solvent was removed by evaporation and the residue was purified by column chromatography eluting with methylene chloride/acetonitrile/methanol (60/35/5). The purified solid was dissolved in methylene chloride/methanol and 5M ethereal hydrogen chloride (2 ml) was added. The volatiles were removed by evaporation, the solid residue was suspended in ether, collected by filtration, washed with ether and dried under vacuum to give 4-(4-chloro-2-fluoroanilino)-7-(3-(imidazol-1-yl)propoxy)-6-methoxyquinazoline hydrochloride (114 mg, 36%).
