Reaction Conditions

Reaction Steps

To a solution of methyl 4-oxo-3,4-dihydroquinazoline-7-carboxylate (0.100 g, 0.49 mmol) in DMF (5 mL) was added potassium carbonate (0.135 g, 0.98 mmol) and 3-(trifluoromethyl)benzyl bromide (0.11 mL, 0.74 mmol). The reaction mixture was heated to 60° C. and stirred overnight. The mixture was then cooled to rt and concentrated. Water was added and the reaction mixture was extracted with DCM (15 mL, 3×). The combined organic phases were then washed with water, and brine, dried over anhydrous Na2SO4, filtered and concentrated to afford methyl 4-oxo-3-[3-(trifluoromethyl)benzyl]-3,4-dihydroquinazoline-7-carboxylate. LC-MS: (FA) ES+ 363.
