Procedure

A solution of 3-benzyl-7-chloro-2-[1-(2,2-dimethoxy-ethylamino)-2-methyl-propyl]-3H-quinazolin-4-one (505 mg, 1.17 mmol), benzoyl chloride (247 mg, 1.76 mmol), and triethylamine (179 mg, 1.76 mmol) in methylene chloride (10 mL) was stirred at room temperature for 18 h. The reaction was washed sequentially with 0.5 N HCl, water, 5% NaHCO3, water, and brine. The organic layer was dried (Na2SO4) and concentrated to yield the title compound as an orange oil (338 mg, 54%). MS(ES+) m/e 534 [M+H]+.
