Reaction Steps

Ethyl 5-[4-(1-methyl-1-{4-methyl-5-[2-(trifluoromethyl)phenyl]-4H-1,2,4-triazol-3-yl}ethoxy)phenyl]-1,2,4-oxadiazole-3-carboxylate (251 mg) was suspended in ethanol (5 ml) and a 1M aqueous sodium hydroxide solution (1 ml) was added thereto, followed by stirring for 5 minutes. Water and 1M hydrochloric acid were added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting solid was washed with ethyl acetate to obtain 5-[4-(1-methyl-1-{4-methyl-5-[2-(trifluoromethyl)phenyl]-4H-1,2,4-triazol-3-yl}ethoxy)phenyl]-1,2,4-oxadiazole-3-carboxylic acid (207 mg), as a white solid.
