Reaction Steps

To a solution of chlorobis(4-chlorophenyl)methane (407 mg, 1.5 mmol) in MeCN was added piperazin-2-one (601 mg, 6.0 mmol) followed by triethylamine (626 μl, 4.5 mmol) and the resulting mixture was refluxed overnight. After cooling to rt, the solvent was evaporated to dryness and the residue was submitted to column chromatography (SiO2, DCM to DCM/MeOH=100:5) to give 4-(bis(4-chlorophenyl)methyl)piperazin-2-one (420 mg) as a white solid.
