实验步骤: A solution of 34.7 g of 2-[4-(3,5-dichloro-2-pyridyloxy)-phenoxy]-propionyl chloride in 80 ml of toluene was added dropwise at 0° to 10° C. to a solution of 16.8 g of 2-benzylthioethanol and 10.1 g of triethylamine in 100 ml of toluene whilst stirring. After the addition was completed, the mixture was stirred further at 30° to 40° C. for 1 hour. The mixture was washed successively with a 1% aqueous solution of sodium hydroxide and water, and dried. Upon distilling off the toluene under reduced pressure, there were obtained 44.9 g of 2-benzylthioethyl 2-[4-(3,5-dichloro-2-pyridyloxy)-phenoxy]-propionate in the form of a colorless viscous oil. nD20 =1.5940. After the addition the mixture was stirred further at 30° to 40° C. for 1 hour The mixture was washed successively with a 1% aqueous solution of sodium hydroxide and water dried Upon distilling off the toluene under reduced pressure

实验步骤: A solution of 21.6 g of 2-bromopropionyl bromide in 30 ml of toluene was added dropwise to a solution of 10.1 g of triethylamine and 16.8 g of 2-benzylthioethanol in 150 ml of toluene at room temperature whilst stirring. After the addition was completed, the reaction mixture was stirred for a further 2 hours at room temperature. The mixture was then washed successively with 1% strength by weight aqueous solution of sodium hydroxide and water. After drying the organic phase over anhydrous sodium sulphate, the toluene was distilled off under reduced pressure, and the end product of 2-benzylthioethyl 2-bromopropionate was obtained in a yield of 28.8 g as a colorless product. nD20 =1.5570. After the addition the reaction mixture was stirred for a further 2 hours at room temperature The mixture was then washed successively with 1% strength by weight aqueous solution of sodium hydroxide and water After drying the organic phase over anhydrous sodium sulphate the toluene was distilled off under reduced pressure
