Reaction Steps

Thionyl chloride (0.32 g, 2.77 mmol) was added dropwise to a suspension of 2-(4-(4-methylpiperazin-1-yl)phenyl)acetic acid (2.60 g, 11.1 mmol) in MeOH (30 ml) at 0° C. and refluxed for 5 h. The reaction mixture was concentrated and the residue was dissolved in water, made alkaline with saturated sodium bicarbonate solution up to pH-8 and extracted with DCM. The organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and evaporated to dryness to get the crude compound. The crude was purified by column chromatography over neutral alumina using 4% MeOH in DCM as eluent to afford 250 mg of methyl 2-(4-(4-methylpiperazin-1-yl)phenyl)acetate as brown color solid.
