实验步骤: After dissolving (2-bromo-6-fluorophenyl)methanol (CAS 261723-33-5) (4.07 g) in toluene (50 ml), thionyl chloride (2.21 ml) was added dropwise while stirring on ice. N,N-Dimethylformamide (0.1 ml) was then added and the mixture was stirred for 6 hours. The reaction mixture was diluted with water, a 1N aqueous solution of sodium hydroxide was added and extraction was performed with ethyl acetate. The organic layer was washed with brine and dried over anhydrous magnesium sulfate. After filtration, the solvent was distilled off under reduced pressure to obtain the title compound (4.45 g). was added dropwise the mixture was stirred for 6 hours extraction The organic layer was washed with brine dried over anhydrous magnesium sulfate After filtration the solvent was distilled off under reduced pressure

实验步骤: 20.0 g (0098 mol) of 2-bromo-6-fluorobenzaldehyde are dissolved in 500 ml of methanol and cooled in an ice bath; 3.72 g (0.098 mol) of sodium borohydride are then added thereto, portionwise. The mixture is stirred under cold conditions for 1 hour and the solvent is then evaporated off under reduced pressure. The residue is taken up between water and dichloromethane, and the organic phase is separated, dried and concentrated under reduced pressure. The residue is crystallized from pentane. 18.1 g of compound are obtained. cooled in an ice bath the solvent is then evaporated off under reduced pressure the organic phase is separated dried concentrated under reduced pressure The residue is crystallized from pentane
