Procedure

To a solution of tert-butyl 3-{[1-(3-benzyl-7-chloro-4-oxo-3,4-dihydroquinazolin-2-yl)-2-(dimethylamino)-2-oxoethyl]amino}propylcarbamate (500 mg, 1 eq.) in methylene chloride (5 ml), was added 4-methyl benzoyl chloride (380 ul, 3 eq.) and triethylamine (660 ul, 5 eq.). The reaction mixture was stirred at room temperature overnight. The solvent was evaporated and the crude product was dissolved in ethyl acetate. Ethyl acetate layer was washed with water, saturated sodium carbonate, saturated sodium chloride, dried over magnesium sulfate, filtered, and evaporated to yield crude tert-butyl 3-[[1-(3-benzyl-7-chloro-4-oxo-3,4-dihydroquinazolin-2-yl)-2-(dimethylamino)-2-oxoethyl](4-methylbenzoyl)amino]propylcarbamate.
