Reaction Steps

(2R)-4-{4-[2-fluoro-3-methyl-4-(tetrahydro-2H-pyran-2-yloxy)phenyl]-2-oxopyridin-1(2H)-yl}-2-methyl-2-(methylsulfonyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (335 mg, 0.58 mmol) was dissolved in 3 mL of dioxane. To this solution was added 1 mL of 4M HCl in dioxane 1 mL of water. The resulting solution was stirred at RT for 10 minutes. The material was diluted up with methanol and concentrated (3×). Dichloromethane was added and the mixture was stirred for 18 h. The solution retained color and a fine particulate was suspended. The mixture was filtered leaving 13.3 mg (6%) of white solid.
