Reaction Steps
3-(chlorosulfonyl)benzoic acid (200 mg, 0.906 mmol) was added to the 1-methylpiperazine (100 mg, 0.997 mmol) in presence of potassium carbonate (251 mg, 1.813 mmol) in THF (Volume: 5 ml) at room temperature and the reaction mixture was stirred for 12 h at room temperature. Reaction was monitored by TLC. After completion of the reaction, the solvent was removed by vacuum and then compound was purified by column chromatography (3% CH3OH/CH2Cl2) afforded the product 3-((4-methylpiperazin-1-yl)sulfonyl)benzoic acid (100 mg, 0.320 mmol, 35.3% yield) as a solid. 1H NMR (CDCl3, 400 MHz): δ 7.77 (m, 2H), 7.63-7.55 (m, 2H), 3.04 (m, 4H), 2.46 (m 4H), 2.31 (s, 3H). Mass [M+H]+:285.1
