Versuchsvorschrift

To a solution of 2-amino-4-methylbenzamide (3 g, 20.0 mmol) in THF (40 mL) was added 5-(4-fluorophenyl)-1,3-dioxolane-2,4-dione from Example 16 (4.7 g, 24 mmol) and the solution was stirred for 2 h at 50° C. Sodium methoxide in MeOH (25%, 5.2 mL, 24 mmol) was then added and the solution was stirred at 50° C. overnight. The reaction mixture solution was concentrated, 2N HCl was added and the mixture was filtered. The collected solid was dried to give 2-(((4-fluorophenyl)(hydroxy)methyl)-7-methylquinazolin-4-ol (5.14 g, 91%) which was used without further purification. LC-MS (ESI) m/z 285 (M+H)+.
