反应步骤

To a solution of (4-bromo-phenyl)-methanol (4.54 g, 24.3 mmol) in N,N-dimethylformamide (50 mL) was added sodium hydride (999 mg, 25 mmol, 60% in oil) under nitrogen atmosphere on an ice bath (0° C.), which was stirred for 30 minutes at room temperature. 2-Fluoro-6-methylpyridine (1.8 g, 16.2 mmol) was then added to the reaction mixture on an ice bath (0° C.), and stirred for 5 hours at room temperature. The reaction mixture was partitioned into water and ethyl acetate on the ice bath (0° C.). The organic layer was washed with water and saturated aqueous sodium chloride, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:heptane=1:15) to obtain the title compound (3.65 g, 81%).
