Methyl 3-(pyrrolidin-1-ylsulfonyl)benzoate (150 mg, 0.557 mmol) was added to the hydrazine (35.7 mg, 1.114 mmol) in methanol and refluxed for 12 h at 65° C. Following cooling, reaction was monitored by TLC. After completion of the reaction, the solvent was removed by vacuum and then compound was purified by column chromatography to yield 3-(pyrrolidin-1-ylsulfonyl)benzohydrazide (110 mg, 0.396 mmol, 71.1% yield). 1H NMR (CDCl3, 400 MHz): δ 8.18 (m, 1H), 8.03 (d, 1H, J=7.6 Hz), 7.97 (d, 1H, J=8.0 Hz), 7.78 (bs, 1H), 7.63 (t, 1H, J=7.6 Hz), 4.17 (bs, 2H), 3.25 (m, 4H), 1.77 (m, 4H). Mass [M+H]+: 270.1
