After concentration in vacuo and dissolving the residue in EtOAc, the organics were washed with H2O, then brine, dried (Na2SO4), filtered, and concentrated in vacuo. Purification by flash chromatography on silica gel, eluting with 10% to 70% EtOAc in heptane, afforded 3-(4-chlorophenyl)-2-(3-methyl-4-nitrophenyl)quinazolin-4(3H)-one (0.300 g, 48%).
