N-(4-Bromo-3-methyl-5-isoxazolyl)-5-(4-chlorobenzamidomethyl)thiophene-2-sulfonamide was prepared in the same manner as described in Example 2 from 5-amino-4-bromo-3-methylisoxazole and 5-(4-chlorobenzamidomethyl)thiophene-2-sulphonyl chloride in 27% yield. The crude product was passed through a silica gel column using hexanes/ethyl acetate as eluent. Purification was effected by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p. 210° C. (dec).
