実験手順
To a round bottom flask is added 3-[5-(2-amino-pyrimidin-5-yl)-1-tert-butyl-1H-benzimidazol-2-yl]-4-1,2,4-triazol-1-yl-benzonitrile (Example 7) (200 mg, 0.46 mmol) in MeOH (5 mL), followed by the addition of NH4OH (2 mL) and H2O2 (1 mL) (30% in water). The reaction mixture is stirred at room temperature for 3 hours. The reaction mixture is diluted with EtOAc (20 mL), washed with water (10 mL), brine (5 mL), dried under anhydrous Na2SO4 (500 mg), filtered and concentrated. The residue is purified by silica gel flash column chromatography with 10% MeOH in CH2Cl2 as the eluent to afford the title compound (89 mg, 42%) as a white solid. LCMS (ESMS): m/z 454.73 (M++1)
