Reaction Steps
According to the above-described scheme, 2-(4-acetylphenyl)-2,2-difluoroacetic acid ethyl ester (Compound 2e; 436.0 mg, 1.8 mmol) and 1N NaOH solution (3.0 mL) were put into an eggplant flask, and the mixture was stirred at 100° C. for 1.5 hours. After the reaction, the reaction mixture was neutralized with 5% HCl solution, extracted with ethyl acetate and washed with water, and an organic layer was dried with anhydrous sodium sulfate. Ethyl acetate was distilled away under reduced pressure, and by carrying out purification by silica gel column chromatography, 2-(4-acetylphenyl)-2,2-difluoroacetic acid (Compound 4e) was obtained with a yield of 96%.
