Reaction Steps

A solution of 1.0 M aq HCl (15 mL) was added slowly to a solution of (2R)-4-[5-fluoro-4-(4-isoxazol-3-ylphenyl)-2-oxopyridin-1(2H)-yl]-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (655 mg, 1.23 mmol) in 1,4-dioxane (30 mL) at rt. The reaction was allowed to stir at rt overnight. The reaction was concentrated to a crude material. Water (30 mL) was added to the crude material and the mixture was boiled for 5 minutes. The mixture was allowed to cool to rt and the solid that formed was collected via filtration and dried under high vacuum to afford the title compound as a light yellow solid (314 mg, 56.9%).
