Reaction Steps
A mixture of 2-chloro-1H-benzimidazole (0.23 g), 4-(3-methoxy-1H-pyrazolo[3,4-b]pyridin-1-yl)phenol (0.24 g) and triethylamine (1.0 ml) was stirred under a nitrogen atmosphere at 160° C. for 7 hr. The reaction mixture was cooled to room temperature, and methanol was added to the reaction mixture. The precipitated solid was filtered off, silica gel was added to the filtrate, the solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate). Then, it was purified by HPLC(C18) (mobile phase: water/acetonitrile (0.1% TFA-containing eluents)) to give the title compound (0.047 g).
