实验步骤: To a solution of methyl 2-hydroxy-3,4-dimethyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (0.50 g) in DME (12.0 mL) were added 4-(bromomethyl)-1-fluoro-2-methoxybenzene (0.39 g), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) dichloromethane adduct (0.07 g) and 2 mol/L aqueous sodium carbonate solution (1.63 mL), and the mixture was stirred overnight at 80° C. under argon atmosphere. The reaction mixture was allowed to be cooled to room temperature, and diluted with ethyl acetate, and the mixture was washed with saturated brine. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (0.45 g). to be cooled to room temperature the mixture was washed with saturated brine The organic layer was dried over anhydrous sodium sulfate the solvent was evaporated under reduced pressure The residue was purified by silica gel column chromatography (ethyl acetate/hexane)

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

实验步骤: 41.7 g (297.54 mmol) of 2-fluoro-5-methylanisole is refluxed overnight with 59.9 g (327.48 mmol) of N-bromosuccinimide and 145 mg of benzoyl peroxide in 945 ml of carbon tetrachloride. The reaction mixture is filtered [through] a glass-fiber filter, and after the solvent is spun off, the residue (72.85 g>100%) is incorporated in crude form into the next stage. The reaction mixture is filtered [through] a glass-fiber filter
