Potassium Carbonate → Methyl 2-methoxy-4-(4-methylpiperazin-1-yl)benzoate

Participants

Reaction Steps

Methyl 2-methoxy-4-fluoro-benzoate (1.6 gr, 9.7 mmol), K2CO3 (1.3 gr, 9.7 mmol) and N-methyl piperazine (1.3 mL, 11.7 mmol) were heated at 100° C. in DMSO (5 mL) for 20 hours. Reaction mixture was diluted with DCM and washed with water. Organic phase was dried over sodium sulfate and evaporated to dryness. Column chromatography purification on silica gel using dichloromethane/methanol 95:5 as the eluant, afforded 1.7 g (yield 66%) of the title compound.
