実験手順

To a solution of 2,3,6-trifluorobenzyl alcohol (41 g) in dichloromethane (100 ml) is added dropwise a solution of thionyl chloride (50 ml) in dichloromethane (80 ml) under ice cooling with stirring, and the mixture is stirred at room temperature overnight. To the mixture is added triethylamine (10 ml), and the solvent is distilled off under reduced pressure to give 2,3,6-trifluorobenzyl chloride (28.6 g), as colorless oil, b.p. 63° C. (13 mmHg).
