实验步骤: A mixture of 300 mg of 1-[bis(4-fluorophenyl)methyl]-3-methylpiperazine and 252 mg of N-(2,4,6-trimethylphenyl) chloroacetamide was dissolved in 20 ml of a 1:1 by volume mixture of tetrahydrofuran and N,N-dimethylformamide. 100 mg of anhydrous potassium carbonate were then added to the solution, and the reaction mixture was stirred at 70° C. for 3 hours, after which ethyl acetate was added to it 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 then removed by evaporation under reduced pressure, and the residue was subjected to silica gel thin layer chromatography using a 1:1 by volume mixture of cyclohexane and ethyl acetate as the developing solvent, to afford a purified 1-[bis(4-fluorophenyl)methyl]-4-[(2,4,6-trimethylphenyl)carbamoylmethyl]-3-methylpiperazine. the organic layer was separated The organic layer was washed three times with water dried over anhydrous magnesium sulfate The solvent was then removed by evaporation under reduced pressure by volume mixture of cyclohexane and ethyl acetate as the developing solvent

实验步骤: 2 g of anhydrous potassium carbonate were added to a mixture of 192.6 mg of 1-(4-chlorobenzhydryl)piperazine and 142.7 mg of N-(2,4,6-trimethylphenyl)chloroacetamide dissolved in 20 ml of N,N-dimethylformamide, and the reaction mixture was stirred at 80° C. for 7.5 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 the solvent was evaporated off under reduced pressure. The residue was subjected to silica gel thin layer chromatography using a 1:1 by volume mixture of cyclohexane and ethyl acetate as the developing solvent, to afford a purified 1-(4-chlorobenzhydryl)-4-(2,4,6-trimethylphenylcarbamoylmethyl)piperazine. the organic layer was separated The organic layer was washed three times with water the solvent was evaporated off under reduced pressure by volume mixture of cyclohexane and ethyl acetate as the developing solvent

实验步骤: N-(Chloroacetyl)-2,4,6-trimethylaniline (443.2 mg), N-pentyl-N-[[2′-[N-(triphenylmethyl)tetrazol-5-yl]-1,1′-biphenyl-4-yl]methyl]amine (780.0 mg), potassium iodide (129.1 mg) and triethylamine (1.15 g) were suspended in dimethylformamide (6 mL). The resulting mixture was heated to about 80° C., and then stirred at that temperature. Three hours later, the reaction mixture was cooled, ethyl acetate (50 mL) was added, and the mixture was washed four times with brine (100 mL, each). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was subjected to chromatography on a silica gel column (hexane/ethyl acetate) to afford N-pentyl-N-[[[(2,4,6-trimethylphenyl)amino]carbonyl]methyl]-N-[[2′-[N-(triphenylmethyl)tetrazol-5-yl]-1,1′-biphenyl-4-yl]methyl]amine (395.4 mg). Yield: 39%. Three hours later, the reaction mixture was cooled the mixture was washed four times with brine (100 mL The organic layer was dried over anhydrous sodium sulfate concentrated under reduced pressure
