Thionyl Chloride → 2-(4-Chloro-2-chloromethyl-phenoxy)-1-[4-(4-fluoro-benzyl)-2,5-dimethyl-piperazin-1-yl]-ethanone

Participants

Reaction Steps

To 2-(4-chloro-2-hydroxymethyl-phenoxy)-1-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-ethanone (0.55 g, 1.3 mmol) in methylene chloride (6 ml) was added thionyl chloride (0.26 ml, 3.58 mmol). The reaction was heated to reflux for 2 hours. After cooling the reaction was quenched by the addition of water. The organic layer was washed with saturated sodium bicarbonate followed by saturated aqueous sodium chloride. The organic layer was then concentrated to afford the title compound as a yellow oil (0.52 g).
