Reaction Steps

Methyl 3-((4-methylpiperazin-1-yl)sulfonyl)benzoate (200 mg, 0.670 mmol) was added to the hydrazine (43.0 mg, 1.341 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 flash chromatography (3% methanol/DCM) to yield the 3-((4-methylpiperazin-1-yl)sulfonyl)benzohydrazide (125 mg, 0.406 mmol, 60.6% yield) as a white solid. 1H NMR (DMSO-d6, 400 MHz): δ 10.08 (s, 1H), 8.12 (m, 2H), 7.84 (d, 1H, J=7.6 Hz), 7.72 (t, 1H, J=7.6 Hz), 4.57 (m, 1H), 2.88 (m, 4H), 2.32 (m, 4H), 2.10 (s, 3H). Mass [M+H]+:298.9
