After purging the vapor phase moiety with hydrogen gas, the mixed solution was stirred at 60° C. under atmospheric pressure while continuously supplying hydrogen. As the time passed, the reaction solution was sampled and analyzed by means of a gas chromatograph. As a result, it was confirmed that 2,3,5,6-tetrafluorobenzyl alcohol was produced together with 2,3,5,6-tetrafluorobenzaldehyde. The yields in the reaction solution are shown in the table below.
