2-Methyl-2-(methylsulfonyl)-4-(4-phenoxyphenyl)-N-(tetrahydro-2H-pyran-2-yloxy)butanamide (247.2 mg, 0.552 mmol) was dissolved in methylene chloride (10 mL) at ambient temperature. To this solution was added HCl (4M in 1,4-dioxane, 4.14 mL, 16.6 mmol) and the solution was stirred at RT for 5 minutes. Methanol (500 uL) was added followed by silica gel and the mixture was concentrated to dryness. The crude material was purified via silica gel chromatography eluting with methylene chloride/methanol to afford N-hydroxy-2-methyl-2-(methylsulfonyl)-4-(4-phenoxyphenyl)butanamide as a solid. 94.4 mg. LCMS: (M−1) 362.3
