Procedure

After adding 150 mg of 5-chloromethyl-2,4-dihydro-[1,2,4]triazol-3-one, 331 mg of 4-(2-fluorophenoxymethyl)piperidine hydrochloride and 180 mg of anhydrous potassium carbonate to acetonitrile, the mixture was stirred overnight at room temperature. Water and ethyl acetate were added to the reaction mixture and the insoluble portion was filtered out to obtain the title compound (70 mg, 21% yield).
