Triethylamine → N-cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl]hexanesulfonamide

Participants

Reaction Steps

1-[(3-Chlorophenyl)phenylmethyl]piperazine (543.7 mg, 1.90 mmol) and N-cyclopropyl-6-chlorohexanesulfonamide (500 mg, 2.09 mmol) were refluxed in toluene (15 ml) in the presence of triethylamine (211 mg, 2.09 mmol) for 48 hours. The reaction mixture was washed with water, and the organic layer was dried over anhydrous magnesium sulfate. Subsequently, the solvent was removed by evaporation in vacuo. The resulting crude product was purified by column chromatography on silica gel with chloroform-methanol (20:1), to give N-cyclopropyl-6-[4-[(3-chlorophenyl)phenylmethyl]-1-piperazinyl]hexanesulfonamide (482.7 mg) as an oil (yield based on 1-[(3-chlorophenyl)phenylmethyl]piperazine: 52.0%).
