실험 절차

A solution of Example C2 (0.100 g, 0.238 mmol) in DCM (5 mL) was treated with mCPBA (0.059 g, 0.238 mmol), stirred at RT for 2 h, treated with t-butylamine (0.4 mL, 3.81 mmol) and stirred at RT overnight. Additional t-butylamine (0.4 mL, 3.81 mmol) was added and the mixture stirred at RT for an additional 24 h. The mixture was concentrated to dryness, transferred to a sealed vessel with DMF (5 mL), treated with additional t-butylamine (0.4 mL, 3.81 mmol) and heated at 60° C. overnight. The mixture was cooled to RT, the solids removed via filtration and washed with DCM. The filtrate was treated with satd. NaHCO3, extracted with DCM (3×) and the combined organics were washed with 5% LiCl (3×), then brine, dried over Na2SO4, concentrated to dryness and purified via silica gel chromatography (MeOH/DCM) to afford N-(tert-butyl)-4-methoxy-5-(6-methyl-5-((2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yl)oxy)pyridin-2-yl)pyrimidin-2-amine (69 mg, 65%). MS (ESI) m/z: 446.3 (M+H+).
