Reaction Steps

Methyl 3-((4-methylpiperidin-1-yl)sulfonyl)benzoate (100 mg, 0.336 mmol) was added to the hydrazine (21.55 mg, 0.673 mmol) in methanol and refluxed for 8 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-((4-methylpiperidin-1-yl)sulfonyl)benzohydrazide (70 mg, 0.217 mmol, 64.4% yield). 1H NMR (CD3OD, 400 MHz): δ 8.16 (m, 1H), 8.05 (m, 1H), 7.91 (m, 1H), 7.70 (t, 1H, J=7.6 Hz), 3.74 (m, 2H), 2.28 (m, 2H), 1.69 (m, 2H), 1.32-1.16 (m, 3H), 0.90 (d, 3H, J=6.0 Hz).
