Piperazine → HCID 59716935, compound

Participants

Reaction Steps

A mixture of 4-(chloro(4-fluorophenyl)methyl)-1-methylpiperidine (1.2 g, 4.12 mmol) in butanone (10 ml), anhydrous piperazine (1.43 g, 16.48 mmol), anhydrous K2CO3 (0.54 g, 4.14 mmol) and KI (0.65 g, 4.14 mmol) was refluxed under nitrogen for 18 hours. The mixture was then cooled and filtered and the solvent removed in vacuo. The residue was dissolved in CH2C12 (50 ml) and washed with water (30 ml). Drying and removal of the solvent followed by chromatography (CH2C12:CH3OH:NH4OH 90:10:0.5) afforded desired product in 62% yield.
