실험 절차
3-(Morpholinosulfonyl)benzoic acid (100 mg, 0.369 mmol) was refluxed overnight in methanol in the presence of catalytic concentrated H2SO4 at 65° C. The 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 the title compound as an off white solid (60 mg). 1H NMR (400 MHz, CDCl3): δ 8.38 (t, 1H, J=1.6 Hz), 8.27 (m, 1H), 7.92 (m, 1H), 7.64 (t, 1H, J=8.0 Hz), 3.95 (s, 3H), 3.73 (m, 4H), 3.00 (m, 4H). ESI-MS: 286.1 [M+H]+.
