Reaction Steps

After adding 150 mg of 5-chloromethyl-2,4-dihydro-[1,2,4]triazol-3-one, 335 mg of 2-(2-fluorophenyl)-1-(piperidin-4-yl)ethanone hydrochloride and 180 mg of anhydrous potassium carbonate to acetonitrile, the mixture was stirred overnight at room temperature. Water was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was washed with water and saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. Diethyl ether was added to the residue and the mixture was filtered to obtain the title compound (23 mg, 7% yield).
