| Reactant | 4,5-Dibromothiophene-2-sulfonyl chloride | HCID 522755 | — |
| Reactant | 4-Bromo-3-methylisoxazol-5-amine | HCID 10487519 | — |
| Product | HCID 15342059 | HCID 15342059 | 45% |
Reaction Steps
N-(4-bromo-3-methyl-5-isoxazolyl)-4,5-dibromothiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-bromo-3-methylisoxazole and 4,5-dibromothiophene-2-sulphonyl chloride in 45% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 153°-155° C.
