A mixture of 416 mg of 1-[bis(4-fluorophenyl)methyl]-2,5-dimethylpiperazine and 316 mg of N-(4-methoxyphenyl)chloroacetamide was dissolved in 5 ml of a 1:1 by volume mixture of tetrahydrofuran and N,N-dimethylformamide. 365 mg of anhydrous potassium carbonate were then added to the solution, and the reaction mixture was stirred at 80° C. for 5 hours. At the end of this time, ethyl acetate was added to the mixture, and the organic layer was separated. The organic layer was washed three times with water, and then dried over anhydrous magnesium sulfate. The solvent was removed by evaporation under reduced pressure, and the residue was subjected to silica gel thin layer chromatography using a 2:1 by volume mixture of cyclohexane and ethyl acetate as the developing solvent, to afford a purified 1-[bis(4-fluorophenyl)methyl]-4-[(4-methoxyphenyl) carbamoylmethyl]-2,5-dimethylpiperazine, melting at 131° C.
