Procedure

To 4-[5-(3-methyl-5-{[4-(methylsulfanyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-1,4-diazepan-2-one (50 mg, 0.117 mmol) stirring in dichloromethane (586 μL) at room temperature was added 3-chloroperbenzoic acid (27.6 mg, 0.123 mmol). Stirred for 3 hr. at room temperature, diluted with 10% Na2S2O3 (aq.), and washed with sat. NaHCO3 (aq.) and brine. The organic extracts were dried (Na2SO4), filtered, and concentrated in vacuo. Purified by reverse phase preparative HPLC (0:100 to 95:5 acetonitrile:water: 0.1% v/v trifluoroacetic acid modifier) to afford 4-[5-(3-methyl-5-{[4-(methylsulfinyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-1,4-diazepan-2-one (3.3 mg, 7.5 μmol, 6.36% yield) as a yellow solid.
