Reaction Steps

To a solution of methyl 4-[6-(3-fluoropyridin-4-yl)-5-pyridin-3-yl-3H-imidazo[4,5-b]pyridin-2-yl]benzoate (Example 10, 0.041 g, 0.097 mmol) in a mixture of THF/ethanol 1:1 (1.2 mL), 2N sodium hydroxide aqueous solution (0.1 mL) was added. The mixture was heated at 60° C. for 3 h and then neutralised with 2N hydrogen chloride aqueous solution. The solvent was evaporated and the crude mixture was purified by silica gel flash chromatography (78:10:10:2 dichloromethane/ethanol/ethyl acetate/acetic acid) to give the title compound (0.013 g, 31% of yield).
