実験手順

To a solution of ethyl 2-methyl-4-(3-methyl-2-oxo-4-phenylpyridin-1(2H)-yl)-2-(methylsulfonyl)butanoate (118.3 mg, 0.313 mmol) in tetrahydrofuran/methanol/water (4:1:1, 3.13 mL) was added lithium hydroxide monohydrate (26.3 mg, 0.626 mmol). The mixture was stirred at ambient temperature overnight. The mixture was diluted with aqueous HCl (1N in water) and extracted with ethyl acetate 2×. The combined organic extracts were dried over magnesium sulfate, filtered and concentrated to dryness to afford 2-methyl-4-(3-methyl-2-oxo-4-phenylpyridin-1(2H)-yl)-2-(methylsulfonyl)butanoic acid as a solid. 109.4 mg.
