| Reactant | (1,1'-Biphenyl)-4-sulphonyl chloride | HCID 74192 | — |
| Reactant | 4-Methyl-3-(trifluoromethyl)isoxazol-5-amine | HCID 15613878 | — |
| Product | N-(4-Methyl-3-trifluoromethyl-5-isoxazolyl)-4-biphenylsulfonamide | HCID 15453174 | 78% |
Reaction Steps
N-(4-Methyl-3-trifluoromethyl-5-isoxazolyl)-4-biphenylsulfonamide was prepared, as described in Example 2, from 5-amino-4-methyl-3-triflouromethylisoxazole and 4-biphenylsulfonyl chloride in 78% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a white solid, m.p. 139-140° C.
