Procedure

A solution of 2-methyl-N-{3-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]oxetan-3-yl}propane-2-sulfinamide (Example 59, Step 2, 75 mg, 0.147 mmol) in dichloromethane (1.5 mL) was cooled to 0° C. m-CPBA (37.8 mg, 0.219 mmol) was added and the resulting mixture was warmed to room temperature. The reaction mixture was diluted with dichloromethane, washed with 2M NaOH (2×), saturated NaHCO3 (1×), brine (1×), dried (Na2SO4), filtered and concentrated. The residue was purified by column chromatography on silica (10-100% ethyl acetate in hexanes) and lyophilized to afford 2-methyl-N-{3-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]oxetan-3-yl}propane-2-sulfonamide (45.6 mg, 0.086 mmol, 59.0% yield) as a light yellow solid.
