| Product | N-(4-Bromo-3-methyl-5-isoxazolyl)-5-bromothiophene-2-sulfonamide | HCID 23445555 | 30% |
Reaction Steps
N-(4-Bromo-3-methyl-5-isoxazolyl)-5-bromothiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-bromo-3-methylisoxazole and 5-bromothiophene-2-sulfonyl chloride in 30% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 240° C. (dec).
