After 1.90 g (43.5 mmol) of 55% sodium hydride were washed with hexane, it was suspended in 25 ml of N,N-dimethylacetamide and 5.3 g (43 mmol) of 4-hydroxybenzaldehyde were gradually added to the suspension at 0° C. under nitrogen atmosphere. When generation of hydrogen gas stopped, 11.14 g (39 mmol) of 2,2,3,3-tetrafluoropropyl p-toluenesulfonate were added to the reaction mixture, followed by heating of the resulting mixture at 120° C. with stirring for 2 hours and 15 minutes. After the reaction mixture was cooled, a mixed solvent of benzene-hexane (1:1) was added thereto and the resulting mixture was washed with water. After drying, the solvent was distilled off to obtain 8.85 g (yield: 96%) of the title compound as an oil.
