Procedure

To 2-methoxyethanol (10 ml) was added NaH (80 mg of a 60% dispersion in mineral oil, 2.0 mmol). The mixture was stirred at room temperature for 10 minutes. Then, 2-acetamido-6-bromo-4-(1,2,4-triazolyl)-quinazoline (167 mg, 0.5 mmol) was added to this solution. The resulting mixture was stirred at room temperature for 30 minutes and then heated at 80° C. for 2 hours. The solvents were evaporated in vacuo and the crude residue was purified by silica gel flash chromatography, the mobile phase being a mixture of methanol and dichloromethane (in a ratio of 1:80), yielding the title compound as a white solid (140 mg, yield: 94%) which was characterized by its mass spectrum as follows: MS (m/z): 298 ([M+H]+, 100).
