Procedure
To a suspension of methyl 2-chloro-3-(4-chlorophenyl)-4-oxo-3,4-dihydroquinazoline-7-carboxylate (0.10 g, 0.23 mmol) in isopropyl alcohol (2.5 mL) was added N,N-diisopropylethylamine (84 μL, 0.48 mmol) and p-chlorobenzylamine (70 μL, 0.57 mmol). The reaction mixture was heated to 100° C. and stirred for 1 h. The mixture was then cooled to rt and concentrated. The residue was purified by flash silica gel chromatography (0% to 50% EtOAc/hexanes) to afford methyl 2-[(4-chlorobenzyl)amino]-3-(4-chlorophenyl)-4-oxo-3,4-dihydroquinazoline-7-carboxylate (46 mg, 44%). LC-MS: (FA) ES+ 456.
