| Product | N-(4-Chloro-3-methyl-5-isoxazolyl)-2-biphenylsulfonamide | HCID 15453178 | 74% |
Reaction Steps
N-(4-Chloro-3-methyl-5-isoxazolyl)-2-biphenylsulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-chloro-3-methylisoxazole and 2-biphenylsulfonyl chloride in 74% yield. Purification was achieved by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 132°-134° C.
