实验步骤: 2-Chloro-6-fluorobenzyl alcohol (50 g) was stirred in dichloromethane and a solution of sodium hydroxide (32 g) in water was added. After 30 minutes stirring the mixture was cooled to 0° C. when dimethyl sulphate (47 g) and tetrabutyl-ammonium hydrogen-sulphate (1 g) were added dropwise. The mixture was allowed to warm to room temperature and stirred for 3 hours. It was quenched with water and extracted with dichloromethane. The organic extract was washed with water, dried (anhydrous magnesium sulphate) and filtered. The filtrate was evaporated to dryness and the residue distilled under reduced pressure yielding 1-chloro-3-fluoro-2-methoxymethylbenzene (27.3 g) b.p. 82°-95° C./24 mm Hg. were added dropwise stirred for 3 hours It was quenched with water extracted with dichloromethane The organic extract was washed with water dried (anhydrous magnesium sulphate) filtered The filtrate was evaporated to dryness the residue distilled under reduced pressure
