Reaction Steps
A mixture of 4-(3-methylpyridin-2-yloxy)benzenamine (1.00 g, 4.99 mmol) and 2-chlorobenzimidazole (0.860 g, 5.64 mmol) in 10 mL of iPrOH was heated at 170° C. for 30 min in the microwave. The reaction mixture was evaporated onto silica gel. Purification by flash chromatography (2M NH3 in MeOH:CH2Cl2) afforded N-(4-(3-methylpyridin-2-yloxy)phenyl)-1H-benzo[d]imidazol-2-amine as solid. MS (ESI, pos. ion) m/z: 317.1 (M+1). IC50 (uM) ++++.
