59% | at 20℃; for 12 h; | A mixture of 4-acetamidobenzene-1-sulfonyl chloride (4.27 mmol), 5-methylisoxazol-3-amine (4.49 mmol) and DMAP (0.21 mmol) in anhydrous pyridine (10 mL) was stirred at room temperature for 12 h. After completion of reaction, solvent was evaporated to dryness and diluted with water and extracted with ethyl acetate. The combined organic layers were washed with water and 1 M aqueous HCl, dried over anhydrous Na2SO4, filtered, and concentrated under vacuum. The solid residue obtained was purified with flash column chromatography using heptanes to EtOAc (50-100percent) gradient elution to afford the compound 2. 4.2.1 N-(4-(N-(5-Methylisoxazol-3-yl)sulfamoyl)phenyl)acetamide (2) Yield: 59percent; ESIMS m/z calcd for C12H13N3O4S [M + H]+, 296.07; found 296.06; 1H NMR (400 MHz, (CD3)2SO): δ 11.30 (bs, 1H), 10.35 (bs, 1H), 7.79-7.73 (m, 4H), 6.12 (s, 1H), 2.29 (s, 3H), 2.07 (s, 3H). 13C (100 MHz, (CD3)2SO): δ 170.71, 169.57, 158.07, 144.01, 133.36, 128.50, 119.15, 95.84, 24.57, 12.48. |
