实验步骤: A 2.5 mol/L sodium hydroxide aqueous solution (2.0 mL, 4.9 mmol), and tetrabutylammonium bromide (0.019 g, 0.58 mmol) were added to 4-ethylbenzenethiol (0.20 g, 1.2 mmol), followed by stirring at 25° C. for 5 minutes. A toluene solution (2.0 mL) of 4-fluoro-3-nitrobenzaldehyde (0.20 g, 1.2 mmol) was added to the reaction liquid, followed by stirring at 25° C. for 12 hours. After the conventional post-reaction treatment, the product was purified by silica gel column chromatography (eluted by chloroform) to give 4-[(4-ethylphenyl)thio]-3-nitrobenzaldehyde (0.25 g, 75%). by stirring at 25° C. for 12 hours After the conventional post-reaction treatment, the product was purified by silica gel column chromatography (eluted by chloroform)

实验步骤: Under a nitrogen atmosphere, 4-ethylbenzenethiol (3.50 ml, 25.4 mmol) and 2-bromo-1,1-dimethoxyethane (3.3 ml, 27.9 mmol) were added to a sodium methoxide methanol solution (0.5 M, 81.4 ml, 40.7 mmol) under cooling with ice. The reaction mixture was stirred at the same temperature for 10 minutes, and then heated to reflux for five hours. The reaction mixture was concentrated under reduced pressure, and cold water was added. The resulting mixture was extracted with ether and the organic layer was washed with a saturated sodium chloride aqueous solution and dried with sodium sulfate. After filtration, the solvent was distilled under reduced pressure and the obtained residue was purified by silica gel column chromatography [developing solution=ethyl acetate:n-hexane (1:20)] to obtain the title compound (5.31 g, 93%). under cooling with ice heated to reflux for five hours The reaction mixture was concentrated under reduced pressure, and cold water was added The resulting mixture was extracted with ether the organic layer was washed with a saturated sodium chloride aqueous solution dried with sodium sulfate After filtration the solvent was distilled under reduced pressure the obtained residue was purified by silica gel column chromatography [developing solution=ethyl acetate:n-hexane (1:20)]
