Procedure

A solution of 2-fluoro-4-iodo-phenyl acetonitrile (Intermediate 2, 2.05 g, 7.83 mmol) in ethanol (50 mL and water (15 mL) was treated with potassium hydroxide (3.4 g, 60.7 mmol) and refluxed for 4 h. 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%).
