14678-02-5, 5-Amino-3-methylisoxazole is a Isoxazoles compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

(a) N-(3-methyl-5-isoxazolyl)-4-bromobenzenesulfonamide 4-brombenzenesulfonyl chloride (solid) was added, in five portions, to a solution of 3-methyl-5-aminoisoxazole (3.82 g, 40 mmol) in dry pyridine (30 ml). This was stirred at room temperature for 3 h and the pyridine was removed under reduced pressure. The residue was dissolved in THF (300 ml) and a 5% NaOH solution (100 ml) was added. Stirring continued for 1 h at room temperature. The THF was removed under reduced pressure and the resultant residue was neutralized to pH 2 using concentrated hydrochloric acid. This was extracted with ethyl acetate (3*200 ml) and the combined organic layer was dried over MgSO4 and concentrated. The crude product was recrystallized using hexane/ethyl acetate giving N-(3-methyl-5-isoxazolyl)-4-bromobenzenesulfonamide (9.2 g, 72% yield).
