実験手順

4-(morpholinosulfonyl)benzoic acid (150 mg, 0.553 mmol) was refluxed in the presence of con. Sulfuric acid (3.57 mg, 0.028 mmol) in methanol at 70° C. for overnight. Reaction was monitored by TLC. After completion of the reaction, solvent was removed by vacuum and then compound was purified by flash chromatography afforded the methyl 4-(morpholinosulfonyl)benzoate (135 mg, 0.464 mmol, 84% yield). 1H NMR (CDCl3, 400 MHz): δ 8.21 (m, 2H), 7.82 (m, 2H), 3.97 (s, 3H), 3.4 (m, 4H), 3.02 (m, 4H). Mass [M+H]+:286.0
