Method for purifying optically active 1-(2-trifluoromethylphenyl)ethanol

摘要

There is disclosed a purification method of an optically active 1-(2-trifluoromethylphenyl)ethanol represented by the formula [1], which includes recrystallizing the optically active 1-(2-trifluoromethylphenyl)ethanol from an aliphatic hydrocarbon solvent where * denotes an asymmetric carbon. This method makes it possible to improve the optical purity of the ethanol significantly.
