Titanium isopropoxide (188 μl, 0.62 mmol) was added to a mixture of 4-(1-isopropyl-2-methylimidazol-5-yl)-2-[4-(methylthio)anilino]pyrimidine (Method 86; 700 mg, 2.06 mmol) in butyl acetate (4.9 ml) and the mixture was heated to 50° C. Cumene hydroperoxide (800 μl, 4.32 mmol) was added over 40 minutes and the mixture was allowed to cool to 20° C. The resulting precipitate was collected by filtration, washed with butyl acetate and dried at 50° C. under vacuum to give the title compound (331 mg, 42%).
