91% | With methanol; sodium tetrahydroborate; at 20℃; for 0.5h;Cooling with ice; | Compound 3 (3.3 g, 11.4 mmol) was added to 60 ml of methanol under an ice bath and then added to NaBH4 (0.93 g, 24.6 mmol) and then moved to room temperature for 0.5 h. Finally, the reaction was quenched with acetone, concentrated, and separated on a silica gel column (PE:EA=3:1) to give 3.03 g of a brown-yellow solid with a yield of 91% and a purity of 96.57% |

67% | With thionyl chloride; In dichloromethane; at 0 - 20℃; for 1.5h; | Compound 4 (2.78 g, 9.5 mmol) was added to 40 ml of DCM, and then at 0 C., thionyl chloride (2.75 ml, 37.8 mmol) was added to the above reaction solution, and the reaction solution was moved to room temperature to react 1.5. h. The reaction mixture was quenched with water and extracted with DCM (X 3), dried over anhydrous magnesium sulfate, concentrated under reduced pressure, and separated on a silica gel column (PE: EA = 4:1) to give 2.0 g of a white solid. Yield 67%, purity 95.7% |
