2,2-二氟-3-甲氧基丙-1-醇

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

实验步骤: To a suspension of sodium hydride (60% in oil, 29 mg) in tetrahydrofuran (5 ml) was added 2,2-difluoro-3-methoxypropan-1-ol (151 mg) at room temperature, and the mixture was stirred at room temperature for 10 min. To the reaction mixture was added 2-(propylsulfanyl)-3-[4-(2,2,2-trifluoroethoxy)phenyl]pyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione (165 mg), and the mixture was stirred at room temperature for 5 hr. The reaction mixture was added to water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane), and recrystallized from a mixed solvent of hexane/ethyl acetate to give the title compound (8 mg). the mixture was stirred at room temperature for 5 hr the mixture was extracted with ethyl acetate The extract was washed with saturated brine dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure The residue was purified by silica gel column chromatography (ethyl acetate/hexane) recrystallized from a mixed solvent of hexane/ethyl acetate
