Reaction Steps

To a solution of 4-(2-amino-pyrimidin-5-yl)-N1-tert-butyl-benzene-1,2-diamine (100 mg, 0.39 mmol) in DMF (5 mL) is added 3-formyl-4-1,2,4-triazol-1-yl-benzonitrile (115 mg, 0.58 mmol) at room temperature. Oxone (239 mg, 0.39 mmol) in H2O (1 mL) is added and the solution is stirred for 3 hours. Saturated sodium thiosulfate solution (5 mL) is added and the mixture is extracted with EtOAc (3×15 mL) and H2O (10 mL). The combined organic layer is dried (MgSO4), filtered and concentrated. The residue is purified by silica gel flash column chromatography eluting with 10% MeOH in CH2Cl2 eluent to afford the title compound (46 mg, 27%) as a white foam. LCMS (ESMS): m/z 436.72 (M++1)
