実験手順: A solution of 2-fluoro-4-iodo-phenyl acetonitrile (Intermediate 2, 3 g, 11.45 mmol) in methanol (50 mL) and benzene (50 mL) was treated with p-toluene sulfonic acid (2.5 g, 13.15 mmol) and heated at reflux overnight using a Dean-Stark water trap. The volatiles were distilled off in vacuo and the residue was diluted with water and diethyl ether. The phases were separated and the organic phase was washed with saturated aqueous sodium bicarbonate (×1), water (×1) and brine (×1), dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford an oil which was subjected to flash column chromatography over silica gel (230-400 mesh) using 6% ethyl acetate in hexane as the eluent to afford the title compound as a colorless oil (2.7 g, 80%). heated at reflux overnight The volatiles were distilled off in vacuo the residue was diluted with water and diethyl ether The phases were separated the organic phase was washed with saturated aqueous sodium bicarbonate (×1), water (×1) and brine (×1) dried over anhydrous magnesium sulfate filtered evaporated in vacuo to afford an oil which

The volatiles were distilled off in vacuo and the residue was diluted with water and poured into cold, dilute hydrochloric acid and the precipitated solid was filtered. The solid was dissolved in diethyl ether, and the organic solution was dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford the title compound a pale yellow solid (1.75 g, 79%). refluxed for 4 h The volatiles were distilled off in vacuo the residue was diluted with water poured into cold, dilute hydrochloric acid the precipitated solid was filtered The solid was dissolved in diethyl ether the organic solution was dried over anhydrous magnesium sulfate filtered evaporated in vacuo

実験手順: A solution of 2-fluoro-4-iodo-benzyl bromide (Intermediate 1, 2.56 g, 8.15 mmol) in ethanol (55 mL and water (10 mL) was treated with sodium cyanide (2.15 g, 43.86 mmol) and refluxed for 0.5 h. The volatiles were distilled off in vacuo and the residue was diluted with water and extracted with diethyl ether (×2). The combined organic extract was washed with water (×1) and brine (×1), dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo to afford the title compound as a pale yellow solid (2.05 g, 96%). refluxed for 0.5 h The volatiles were distilled off in vacuo the residue was diluted with water extracted with diethyl ether (×2) The combined organic extract was washed with water (×1) and brine (×1) dried over anhydrous magnesium sulfate filtered evaporated in vacuo
