实验步骤: Thionyl chloride (0.892 g, 7.5 mmol) was added to a solution of the product of STEP 1 (1.0 g, 6.4 mmol) dropwise at 0° C. After 30 min, the reaction was quenched with crushed ice carefully, and diluted with H2O. The product was extracted with ether. The organic layer washed with saturated NaHCO3, brine and dried with Na0.2SO4. Ether was evaporated and the residue was purified by chromatography (on silica gel, ethyl acetate/hexane=1/9) to give a clear liquid in 10.5 g. NMR spectra of the product were consistent for the proposed structure. the reaction was quenched with crushed ice carefully diluted with H2O The product was extracted with ether The organic layer washed with saturated NaHCO3, brine dried with Na0.2SO4 Ether was evaporated the residue was purified by chromatography (on silica gel, ethyl acetate/hexane=1/9) to give a clear liquid in 10.5 g

实验步骤: 3-fluoro-p-anisaldehyde (12.5 g, 81.1 mmol) was dissolved in 100 ml THF. Under N2 a solution of diisobutylalumium hydride (100 ml, 1M in THF) was added at 0° C. over 30 min. The reaction was stirred for 30 min and quenched with 250 ml 1 N HCl solution. The mixture was stirred for 15 min and filtered through a short column of Celite®. The aqueous layer was extracted with ethyl acetate. The combined organic layer was dried with MgSO4, and concentrated to give an oil in 11.6 g. This product was used without further purification.
