实验步骤: To a solution of 3-bromophenylacetonitrile (12 g, 61.2 mmol) in tetrahydrofuran (150 ml) cooled down to 0° C., was added 60% sodium hydride in mineral oil (2.25 g, 56.3 mmol) portionwise over 10 minutes. The reaction mixture was stirred at 0° C. for 40 minutes. Methyl iodide (5.71 ml, 91.8 mmol) was added dropwise at 0° C. and the reaction mixture was stirred at 0° C. for a further 1 hour. The reaction mixture was diluted with ethyl acetate (250 ml), washed with water and brine. The organic phase was dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel by flash column chromatography (ISCO Companion, 330 g column, 0-20% EtOAc/Petrol) to afford the title compound as a colourless oil (7.06 g, 55% yield). the reaction mixture was stirred at 0° C. for a further 1 hour washed with water and brine The organic phase was dried over magnesium sulfate filtered concentrated in vacuo The residue was purified on silica gel by flash column chromatography (ISCO Companion, 330 g column, 0-20% EtOAc/Petrol)
