A solution of Example C2 (0.15 g, 0.36 mmol) in DCM (5 mL) was treated with mCPBA (0.11 g, 0.43 mmol), stirred at RT for 2 h, treated with pyrrolidine (0.5 mL) and stirred at RT overnight. The mixture was treated with satd. NaHCO3, extracted with DCM (3×) and the combined organics were dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to obtain 4-methoxy-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)-2-(pyrrolidin-1-yl)pyrimidine (100 mg, 63%). MS (ESI) m/z: 444.2 (M+H+).
