Reaction Steps

Jones reagent (1.28 mL, 10.24 mmol) is added dropwise to a solution of N-[3-(2-Hydroxy-1,1-dimethyl-ethyl)-isoxazol-5-yl]-2-methyl-2-(tetrahydro-pyran-4-sulfonyl)-propionamide (560 mg, 1.50 mmol) in a mixture of acetone (4 mL) and dichloromethane (4 mL) at 0° C. The reaction mixture is stirred at 0° C. for 3 minutes then room temperature for 2.5 h. After this time, the reaction mixture is diluted with acetone and filtered through celite and the celite is washed with acetone. The filtrate is concentrated under reduced pressure. The residue is dispersed in water and filtered to yield the title compound. Yield: 64%; m/z 389 [M+H].
