| Reactant | 3-Phenylbenzene-1-sulfonyl chloride | HCID 3802752 | — |
| Reactant | 4-Chloro-3-methyl-1,2-oxazol-5-amine | HCID 10582822 | — |
| Product | N-(4-chloro-3-methyl-5-isoxazolyl)-3-biphenylsulfonamide | HCID 15453180 | 63% |
Reaction Steps
N-(4-chloro-3-methyl-5-isoxazolyl)-3-biphenylsulfonamide was prepared in the same manner as described in Example 204 from 5-amino-4-chloro-3-methylisoxazole and 3-biphenylsulfonyl chloride in 63% yield. This was purified by HPLC (5% CH3CN to 100% CH3CN over 30 min.) to give a solid, m.p. 84-86° C.
