Reaction Steps

To a suspension of 4-hydroxy-6-(4-fluorophenyl)-quinazoline (720 mg, 3 mmol) in toluene (20 ml) was added diisopropylethylamine (1.5 ml, 9 mmol) and POCl3 (0.84 ml, 9 mmol). The mixture was refluxed for 1 hour. The solvents were evaporated in vacuo. The residue was redissolved in dichloromethane and the organic layer was washed with ice water till pH 6-7. The combined organic layers were dried over MgSO4 and concentrated to yield the title compound as a yellow solid (700 mg, yield: 90%) was characterized by its mass spectrum as follows: MS (m/z): 259 ([M+H]+, 100).
