Sodium Thiosulfate → {2-Amino-5-[1-tert-butyl-2-(2-1,2,4-triazol-1-yl-phenyl)-1H-benzimidazol-5-yl]-pyridin-3-yl}-methanol

Participants

Reaction Steps

To a solution of [2-amino-5-(3-amino-4-tert-butylamino-phenyl)-pyridin-3-yl]-methanol (100 mg, 0.35 mmol) in DMF (5 mL) is added 2-[1,2,4]-triazol-1-yl-benzaldehyde (73 mg, 0.42 mmol) at room temperature. Oxone (215 mg, 0.35 mmol) in H2O (1 mL) is added and the solution is stirred for 4 hours. Saturated sodium thiosulfate solution (5 mL) is added and the mixture is extracted with EtOAc (3×10 mL) and H2O (10 mL). The combined organic layer is dried with MgSO4 and is filtered. The filtrate is concentrated and the residue is purified by silica gel flash column chromatography eluting with 10% MeOH in CH2Cl2 to afford the title compound (16 mg, 10%) as a pale brown foam. LCMS (ESMS): m/z 440.20 (M++1)
