Procedure

To a solution of tert-butyl 3-[[1-(7-chloro-4-oxo-3,4-dihydroquinazolin-2-yl)-2-(dimethylamino)-2-oxoethyl](4-methylbenzoyl)amino]propylcarbamate (29 mg, 1 eq.) in dimethyl formamide (1 ml), was added 3-methylbenzyl bromide (8 μl, 1.2 eq.) and potassium carbonate (22 mg, 3 eq.). The reaction mixture was stirred at room temperature overnight. Water was added and the material was extracted into ethyl acetate. Ethyl acetate layer was washed with water, saturated sodium carbonate, saturated sodium chloride, dried over magnesium sulfate, filtered, and evaporated. The product was purified by flash chromatography to give tert-butyl 3-[[1-[7-chloro-3-(3-methylbenzyl)-4-oxo-3,4-dihydroquinazolin-2-yl]-2-(dimethylamino)-2-oxoethyl](4-methylbenzoyl)amino]propylcarbamate.
