Abstract
The present invention relates to a process for making N-(4-fluorophenyl)-N-(1-methylethyl)-2-�(5-(trifluoromethyl)-1,3,4-thiadia zol-2-yl)oxy!acetamide, which process includes the steps of reacting 2-(methylsulfonyl)-5-(trifluoromethyl)-1,3,4,-thiadiazole with N-(4-fluorophenyl)-2-hydroxy-N(1-methylethyl)acetamide in an aprotic, aromatic solvent with aqueous alkali to form an aqueous phase and an organic phase, separating the aqueous and organic phases and recovering the N-(4-fluorophenyl)-N-(1-methylethyl)-2-�(5-(trifluoromethyl)-1,3,4-thi adiazol-2-yl)oxy!acetamide from the organic phase. A preferred solvent and aqueous alkali are toluene and aqueous sodium hydroxide, respectively.
