    摘要: A fluorine-containing benzonitrile derivative (formula 1) is subjected to a reduction reaction to obtain a fluorine-containing benzylamine derivative (formula 2), and the amino group in said fluorine-containing benzylamine derivative is replaced with a hydroxyl group to obtain a fluorine-containing benzyl alcohol derivative (formula 3): wherein X is a halogen atom, when m is an integer of 2 or more, each X may be the same or different, and m is an integer of from 0 to 4.
