Triethylamine → N-(2,6-dimethylphenyl)-2-[4-(4-oxo-4-phenylbutyl)piperazin-1-yl]acetamide

Participants

Reaction Steps

A mixture of N-(2,6-dimethylphenyl)-2-piperazinylacetamide (4) (100 mg, 0.4 mmol), 4-chloro-1-phenylbutan-1-one (12) (100 mg, 0.55 mmol), and triethylamine (0.4 mL) in ethanol (3 mL) was heated at reflux for 16 hours. Ethanol was removed under reduced pressure and the residue was purified by preparative TLC using 10% methanol in dichloromethane as mobile phase to afford N-(2,6-dimethylphenyl)-2-[4-(4-oxo-4-phenylbutyl)piperazin-1-yl]acetamide, a compound of formula (16).
