Procedure
Hydrazine (11.78 mg, 0.367 mmol) was added to the methyl 5-((4-methylpiperazin-1-yl)sulfonyl)nicotinate (55 mg, 0.184 mmol) in methanol (10 mL) and refluxed for overnight. The reaction was monitored by TLC, after completion of the reaction, Solvent was removed by vacuum and then compound was purified by column chromatography (3% methanol/DCM) afforded the title compound 5-((4-methylpiperazin-1-yl)sulfonyl)nicotinohydrazide (45 mg, 0.147 mmol, 80% yield) as a solid. 1HNMR (400 MHz, CDCl3): δ 9.07 (s, 1H), 9.02 (s, 1H), 8.33 (s, 1H), 7.46 (bs, 1H), 4.09 (bs, 2H), 3.05 (m, 4H), 2.43 (m, 4H), 2.21 (s, 3H). ESI-MS: 300.1 [M+H]+
