实验步骤: 366 mmol (26.7 ml) of thionyl chloride are added dropwise to 183 mmol (25 g) of 5-chlorovaleric acid in 250 ml of toluene heated at reflux. The mixture is stirred at reflux until the evolution of gas has ceased and is then cooled. The solvent is evaporated off. The product obtained is then redissolved in 250 ml of dichloromethane and the temperature is lowered to 5° C. A solution of 183 mmol (31.5 g) of 4-bromoaniline in 100 ml of dichloromethane and 183 mmol (25.5 ml) of triethylamine are added in succession. The reaction mixture is stirred for 4 hours at 5° C. and then for 15 hours at room temperature. Hydrolysis, washing the organic phase with a 1N hydrochloric acid solution and evaporating off the solvents yields the expected product, which is used without being purified. heated at reflux at reflux until the evolution of gas is then cooled The solvent is evaporated off The product obtained is lowered to 5° C The reaction mixture is stirred for 4 hours at 5° C.
