The mixture was stirred at ambient temperature for 3 hours, washed with water and brine. The organic layer was dried over magnesium sulfate, and concentrated. The residue was purified by column chromatography eluting with a mixture of methanol and chloroform (1:9) to give (S)-N-(4-acetyl-2-methyl-1-piperazinyl)-4-fluorobenzamide (50 mg).
