Procedure

The 70:30 mixture of products from Step 1 (100 mg, 0.22 mmol) was dissolved in acetone (1 mL) and water (125 μL). Osmium tetroxide (4% in H2O, 548 μL, 0.09 mmol) and 4-methylmorpholine N-oxide (105 mg, 0.90 mmol) were added and the suspension was stirred for 1 h at room temperature. The reaction was quenched with 5% aqueous sodium thiosulfate and stirred for 15 minutes. The mixture was washed with ethyl acetate (3×), and the combined organic layers were dried over sodium sulfate, filtered, and concentrated to give a mixture of 4,5-dihydroxy-5-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]azepan-2-one and 5,6-dihydroxy-5-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]azepan-2-one (70:30, 40 mg, 0.084 mmol 37% yield) as a brownish-yellow solid.
