Reaction in Acetonitrile With Potassium Carbonate. A mixture of 2-[3-[4-(3-chlorophenyl)-1-piperazinyl]propyl]-5-ethyl-1H-1,2,4-triazol-3(2H)-one (15 g., 0.043 mole), phenoxyethyl bromide (8.62 g., 0.043 mole), potassium carbonate (11.9 g., 0.086 mole) and a trace of potassium iodide in 100 ml. of acetonitrile is refluxed for a 64 hr. period. The reaction mixture is filtered, the filtrate concentrated under reduced pressure and residual material taken up in ether and filtered. Concentration of the ethereal filtrate affords 18.35 g. (91%) of the free base product 2-[3-[4-(3-chlorophenyl)-1-piperazinyl]propyl]-5-ethyl-4-(2-phenoxyethyl)-2H-1,2,4-triazol-3(4h)-one. The free base is converted to the hydrochloride in ethanol employing ethanolic hydrogenchloride and crystallized from ethanol to afford a 53% yield of analytically pure 2-[3-[4-(3-chlorophenyl)-1-piperazinyl]propyl]-5-ethyl-4-(2 -phenoxyethyl-2H-1,2,4-triazol-3(4H)-one hydrochloride, m.p. 175°-177° C.
