The present invention relates to a process for isolating N-(4-fluorophenyl)-N-(1-methylethyl)-2-[(5-trifluoromethyl)-1,3,4-thiadiazol-2- yl)oxy]acetamide from a solution of N-(4-fluorophenyl)-N-(1-methylethyl)- 2-[(5-trifluoromethyl)-1,3,4-thiadiazol-2-yl)oxy]acetamide in an aprotic, aromatic solvent. The process includes the steps of: (a) removing the solvent from the solution to form a substantially solvent-free material; (b) melting the material from step (a) to form a molten material; and (c) isolating N-(4-fluorophenyl)-N-(1-methylethyl)-2-[(5-trifluoromethyl)-1,3,4- thiadiazol-2-yl)oxy]acetamide from the molten material by flaking.
