70 °C

Aqueous potassium carbonate solution (20% w/v, 6.07 ml), methanol (12.1 ml) were added to N-(3′-benzyloxy-5-cyano-2-fluoro-3-methoxy-6-methylbiphenyl-4-yl)-2,2,2-trifluoroacetamide (I-53) (400 mg, 873 μmol), followed by stirring overnight at 70° C. After cooling, methanol was evaporated away under reduced pressure, saturated brine (50 ml) was added, the product was extracted with ethyl acetate (50 ml×2). The organic layer was dried over anhydrous magnesium sulfate, concentrated under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=4:1) to obtain the entitled compound (276 mg, 87%) as a colorless solid.
