实验步骤: To a solution of NaH (60% dispersed in oil, 0.731 g, 21.7 mmol) in dry DMF (15 ml) was added Ethyl 3-mercaptopropionate (2.66 g, 19.8 mmol). When the evolution of hydrogen ceased, 4-Hydroxybenzyl bromide from Step A was added. The reaction mixture was stirred for 16 hours at room temperature, quenched with sat. NH4Cl and concentrated in vacuo. The crude residue was taken in EtOAc and washed with water and brine. The aqueous layer was washed one more time with EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated. The purification was done by flash chromatography on silica gel column (dichloromethane:ethyl acetate, 95:5) to provide the title compound. quenched with sat. NH4Cl concentrated in vacuo washed with water and brine The aqueous layer was washed one more time with EtOAc The combined organic layers were dried over Na2SO4 filtered concentrated The purification

实验步骤: To a stirred solution of PBr3 (1.38 g, 5.0 mmol) in dry THF (2 ml) at −5° C. was added a solution of dry pyridine (0.201 ml) in dry THF (0.4 ml). A solution of 4-Hydroxybenzyl alcohol (1.89 g, 15.2 mmol) in dry THF (23 ml) was added drop wise to the reaction mixture. The reaction mixture was allowed to stand at room temperature for 18 hours, then diluted with THF and filtered through celite pad. The filtrate was evaporated, the resulting semisolid was redissolved in dry toluene (16 ml). The solution was maintained at −20° C. for 2 hours, and then filtered through celite pad to provide the title compound as a light yellow solution which was used without further purification. filtered through celite pad The filtrate was evaporated the resulting semisolid was redissolved in dry toluene (16 ml) filtered through celite pad
