Reaction Steps

Benzoyl chloride (0.341 ml, 2.94 mmol) was added dropwise to a stirred mixture of 1-(4-piperazin-1-yl-phenyl)-ethanone (500 mg, 2.45 mmol) and TEA (0.681 ml, 4.9 mmol) in DCM (25 ml). The resulting solution was stirred overnight at room temperature, then diluted with DCM and washed with water, with NaHCO3 (5% in H2O) and finally with citric acid (20% in H2O). The organic phase was dried over Na2SO4 and evaporated in vacuo. The resulting solid was triturated with di-isopropylether and filtered to give 687 mg of 1-[4-(4-benzoyl-piperazin-1-yl)-phenyl]-ethanone.
