实验步骤: (3-Chloro-5-fluoro-phenyl)acetic acid methyl ester (Example 127-(1); 35 mg, 0.173 mmol), palladium acetate (2.7 mg, 0.012 mmol), 2-dicyclohexylphosphino-2′,6′-dimethoxy-1,1′-biphenyl (9.4 mg, 0.023 mmol), potassium phosphate (73 mg, 0.345 mmol) and water (0.2 mL) were added to a solution of (E)-3-ethyl-1-(4-{1-ethyl-1-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-propyl}-2-methyl-phenyl)-1-penten-3-ol (Example 39-(5); 55 mg, 0.115 mmol) in toluene (2 mL). After replacement with nitrogen, the mixture was stirred at 100° C. for two hours. The reaction mixture was then poured into a saturated aqueous sodium bicarbonate solution, followed by extraction with dichloromethane. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (hexane:ethyl acetate=4:1) to give the target compound as a colorless oil (57.7 mg, 97%). followed by extraction with dichloromethane The organic layer was dried over anhydrous magnesium sulfate filtered concentrated under reduced pressure The resulting residue was purified by silica gel chromatography (hexane:ethyl acetate=4:1)

实验步骤: Trimethylsilyldiazomethane (2 M solution in diethyl ether, 0.199 mL, 0.398 mmol) was added to a solution of (3-chloro-5-fluoro-phenyl)acetic acid (50 mg, 0.265 mmol) in methanol (0.5 mL) and toluene (2 mL), and the mixture was stirred at room temperature for 10 minutes. Acetic acid was added to the reaction mixture to terminate the reaction, and then the mixture was concentrated under reduced pressure to give the target compound as a colorless oil (53 mg, 99%). to terminate the reaction the mixture was concentrated under reduced pressure
