3-(5-氯-2-氟苯基)丙-1-醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Compound 64-2 (2.28 g) was dissolved in methylene chloride (40 ml), triphenylphosphine (3.50 g) and N-bromosuccinimide (2.37 g) were added under ice-cooling, and the mixture was stirred under ice-cooling for 5 hr. Water was added to the reaction mixture, and the mixture was extracted with methylene chloride and washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. Diethyl ether was added, and the precipitated triphenylphosphine oxide was filtered off. The concentrate of the filtrate was purified by silica gel column chromatography (hexane alone) to give the object product (2.70 g) as a colorless oil. cooling cooling for 5 hr the mixture was extracted with methylene chloride washed with saturated brine dried over anhydrous sodium sulfate The solvent was evaporated under reduced pressure Diethyl ether was added the precipitated triphenylphosphine oxide was filtered off The concentrate of the filtrate was purified by silica gel column chromatography (hexane alone)
