Reaction Conditions

Reaction Steps

To a solution of 4-fluoro-benzaldehyde (3.0 g, 0.024 mol) and 1-(2,6-dimethyl-piperazin-1-yl)-ethanone (3.0 g, 0.019 mol) in anhydrous DMF (15 mL) was added potassium carbonate (6.6 g, 0.048 mol). The reaction mixture was heated to 130° C. for 32 hours. The DMF was removed and the residue was purified by column chromatography (silica gel 230-400 mesh; eluting with 2:1 ethyl acetate and dichloromethane) to give 4-(4-acetyl-3,5-dimethyl-piperazin-1-yl)-benzaldehyde as light yellow solid (2.31 g, 46.2%).
