Versuchsvorschrift

N-{[6-bromo-1-(4-methoxybenzyl)-3-methyl-2-oxo-4-(trifluoromethyl)-1,2,3,4-tetrahydroquinazolin-4-yl]methyl}4-fluorobenzamide (9.6 mg, 0.017 mmol) was dissolved in acetonitrile (1.0 mL) and water (0.25 mL), and cerium ammonium nitrate (27.2 mg, 0.050 mmol) was added to the reaction solution under ice-cooling. After the reaction solution was stirred at room temperature for 4 hours, chloroform and water were added thereto and the solution was stirred at room temperature. The organic layer was separated and washed with saturated brine and then dried over magnesium sulfate. After the drying agent was removed by filtration, the solvent was evaporated under reduced pressure. The residue was purified by thin-layer chromatography (chloroform/methanol=1/4), whereby the objective N-{[6-bromo-3-methyl-2-oxo-4-(trifluoromethyl)-1,2,3,4-tetrahydroquinazolin-4-yl]methyl}4-fluorobenzamide (4.0 mg, 53%) was obtained as a white solid.
