Procedure

Diethyl azodicarboxylate (295 μl, 1.8 mmol) was added dropwise to a suspension of 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (200 mg, 0.62 mmol), (prepared as described for the starting material in Example 24), 2-(3,5-dimethyl-[1,2,4]-triazol-4-yl)ethanol (114 mg, 0.81 mmol), (EP 0329357 A1), and triphenylphosphine (492 mg, 1.8 mmol) in methylene chloride (4 ml) and the mixture stirred for 1 hour at ambient temperature. The precipitated solid was collected by filtration, washed with ether and dried under vacuum. The solid was dissolved in methylene chloride/methanol and ethereal hydrogen chloride (2 ml of 4.5M solution) was added. The volatiles were removed by evaporation, the residue was suspended in ether, collected by filtration, washed with ether and dried under vacuum to give 4-(4-chloro-2-fluoroanilino)-7-(2-(3,5-dimethyl-[1,2,4]-triazol-4-yl)ethoxy)-6-methoxyquinazoline hydrochloride (184 mg, 54%).
