A stirred mixture of 0.59 g (0.0014 mole) of 4-[2-chloro-4-fluoro-5-(4-difluoromethyl -4,5-dihydro-3-methyl-5-oxo-1H-1,2,4 triazol-1-yl)phenoxy]phenyl-carboxylic acid chloride and 0.17 g (0.0014 mole) of 2-sulfamylpropane was heated at 195° C. for approximately 15 minutes. The mixture was cooled and 2 mL of methylene chloride was added. The mixture was allowed to stand at room temperature for approximately 18 hours. A brown solid formed, was collected and triturated with petroleum ether. Recovery of the solid by filtration gave 0.58 g of N-(1-methylethyl)sulfonyl-4-[2-chloro-4-fluoro-5-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl)phenoxy]phenylcarboxamide as a solid, m.p. 185°-187° C., Compound 130 of Table 1.
