Participants

Reaction Conditions

Reaction Steps

Hydrazine (43.3 mg, 1.352 mmol) was added to the methyl 3-(N-methylsulfamoyl)benzoate (155 mg, 0.676 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-(hydrazinecarbonyl)-N-methylbenzenesulfonamide (120 mg, 0.502 mmol, 74.3% yield). 1H NMR (CDCl3, 400 MHz): δ 8.25 (m, 1H), 8.01 (m, 2H), 7.64 (m, 2H), 4.63 (m, 1H), 4.17 (m, 2H), 2.69 (d, 3H, J=5.2 Hz). ESI-MS: 230.0 [M+H]+
