Participants

Reaction Steps

To a solution of ethyl 4-[4-(benzyloxy)-2-oxopyridin-1(2H)-yl]-2-methyl-2-(methylsulfonyl)butanoate (740 mg, 1.82 mmol) in tetrahyrofuran/methanol/water (4:1:1, 18.2 mL) was added lithium hydroxide monohydrate (152 mg, 3.63 mmol). The mixture was stirred at ambient temperature overnight. The mixture was diluted with aqueous HCl (1N in water) and extracted with ether 2×. The combined organic extracts were washed with water, dried over magnesium sulfate, filtered and concentrated to dryness to afford 4-[4-(benzyloxy)-2-oxopyridin-1(2H)-yl]-2-methyl-2-(methylsulfonyl)butanoic acid as a solid. 674.9 mg.
