| Product | N-(4-Bromo-3-methyl-5-isoxazolyl)-5-(2-pyridyl)thiophene-2-sulfonamide | HCID 15342058 | 40% |
Reaction Steps
N-(4-Bromo-3-methyl-5-isoxazolyl)-5-(2-pyridyl)thiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-bromo-3-methylisoxazole and 5-(2-pyridyl)thiophene-2-sulphonyl chloride in 40% yield. Purification was achieved by recrystallization from ethyl acetate to give a crystalline solid, m.p. 186°-188° C.
