Procedure

HCl (1.0 N in water, 3.58 mL) was added to a solution of (2R)-4-{4-[4-(cis-3-hydroxycyclobutyl)phenyl]-2-oxopyridin-1(2H)-yl}-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (620 mg, 1.20 mmol) in 1,4-dioxane (10 mL). After 2 hours the reaction was concentrated to give a brown solid. The solid was triturated with ethanol at 50° C., for 30 minutes. After cooling, filtration afforded the title compound as a white solid (384 mg, 74%).
