実験手順

Lithium aluminum hydride (0.8 g) is suspended in dry diethyl ether (5 ml) and the mixture is stirred. To the mixture is added dropwise a solution of 2-(2,3,6-trifluorophenyl)acetic acid (2.0 g) in dry diethyl ether (15 ml), and the mixture is refluxed for 30 minutes. To the reaction mixture are added water (0.8 ml), 10% aqueous sodium hydroxide (0.8 ml) and water (1.6 ml) in this order, and the mixture is stirred at room temperature. To the mixture is added diethyl ether (10 ml), and the resulting precipitates are separated by filtration and washed with tetrahydrofuran. The washing liquid and the filtrate are combined and then concentrated under reduced pressure to give 2-(2,3,6-trifluorophenyl)ethyl alcohol (1.9 g), as colorless oil.
