实验步骤: A mixture of 0.71 g (4.0 mmole) of palladium chloride, 2.1 g (8.0 mmole) of triphenylphosphine, 0.80 g (4.2 mmole) of cuprous iodide, 68.8 g (0.21 mole) of 5-chloro-2-iodobenzophenone, 200 ml of diethylamine, and 400 ml of methylene chloride was stirred at room temperature under argon until complete solution was obtained. In one portion, 40.0 g (0.22 mole) of N-propargyl-phthalimide was added to the solution and the resulting mixture stirred for 20 hr. The volatiles were removed at reduced pressure and the residue was triturated with 200 ml of isopropanol. The resulting precipitate was collected by filtration to give the crude product mp 130°-133° C. Recrystallization from acetone gave cream colored prisms, mp 148°-150° C. was obtained the resulting mixture stirred for 20 hr The volatiles were removed at reduced pressure the residue was triturated with 200 ml of isopropanol The resulting precipitate was collected by filtration

实验步骤: A mixture of 0.94 g (2 mmol) of 6-(2-fluorophenyl) 8-iodo-1-(trifluoromethyl)-4H-[1,2,4]triazolo [4,3-a][1,4]-benzodiazepine, 0.55 g (3 mmol) of N-propargylphthalimide 80 mg of triphenylphosphine, 20 mg of cuprous iodide, 0.6 ml of triethylamine and 50 ml of dimethylformamide was degassed with argon for 10 minutes. Palladium acetate, 25 mg. was then added and the mixture was stirred for 3 days at room temperature. The product was precipitated by dilution with sodium bicarbonate solution and was collected by filtration. It was dissolved in methylene chloride and the solution was washed with bicarbonate solution, dried and evaporated. The residue was chromatographed over 40 g of silica gel using 5% (v/v) of ethanol in methylene chloride. The combined good fractions were evaporated and the residue was crystallized from ethyl acetate to give colorless crystals of 2-{3-[6-(2-fluorophenyl)-1-(trifluoromethyl)-4H-[1,2,4]triazolo[4,3-a][4,1]benzodiazepin-8-yl]-2-ProPynyl}-1H-isoindole-1,3(2H)-dione with m.p. 204°-206° . was degassed with argon for 10 minutes was then added The product was precipitated by dilution with sodium bicarbonate solution was collected by filtration It was dissolved in methylene chloride the solution was washed with bicarbonate solution dried evaporated The residue was chromatographed over 40 g of silica gel using 5% (v/v) of ethanol in methylene chloride The combined good fractions were evaporated the residue was crystallized from ethyl acetate
