実験手順

Methyl 3-(morpholinosulfonyl)benzoate (120 mg, 0.421 mmol) was added to hydrazine (17.52 mg, 0.547 mmol) in methanol and refluxed for 12 h at 65° C. The reaction was monitored by TLC. Upon completion of the reaction and cooling the reaction mixture, the solvent was removed by vacuum and then compound was purified by column chromatography to yield the title compound as an off white solid (90 mg). 1H NMR (400 MHz, CDCl3): δ 8.16 (m, 1H), 8.12 (m, 1H), 8.04 (m, 1H), 7.85 (m, 1H), 7.63 (t, 1H, J=8.0 Hz), 4.19 (m, 2H), 3.71 (m, 4H), 2.97 (m, 4H). ESI-MS: 286.1 [M+H]+.
