To a solution of 3-(2-hydroxymethyl-3-methyl-benzyloxy)-phenol (87 mg, 0.38 mmol, example 100) and (3-methyl-4-oxo-3,4-dihydro-quinazolin-2-yl)-methyl chloride (94 mg, 0.45 mmol, example 99) in DMF (1 mL) is added powdered K2CO3 (78 mg, 0.5 mmol). The resulting mixture is warmed to 60° C. and stirred at this temperature for 5 h. This mixture is cooled to room temperature, diluted with ethyl acetate, washed with water and brine, dried over MgSO4 and concentrated. The residue is purified by flash chromatography (silica, 40% ethyl acetate/30% dichloromethane in hexanes) to give the title compound as a foam. MS (ESI) 417 (M+H)+.
