Procedure

2-(2,3,6-Trifluorophenyl)acetonitrile (13.3 g) is dissolved in ethanol (20 ml), and thereto is carefully added conc. sulfuric acid (8.5 ml), and the mixture is refluxed at 125° C. for 7 hours. After cooling, the reaction mixture is fractionated with diethyl ether and water. The ether layer is washed with aqueous saturated sodium chdloride and dried over magnesium sulfate and then concentrated under reduced pressure to give ethyl 2-(2,3,6-trifluorophenyl)acetate (16.3 g), as colorless oil.
