Reaction Steps

A solution of 6-(3-fluoropyridin-4-yl)-2-hydrazino-5-pyridin-3-yl-3H-imidazo[4,5-b]pyridine (0.05 g, 0.15 mmol), pentane-2,4-dione (0.016 mL, 0.16 mmol) and hydrogen chloride aqueous solution in ethanol (1 mL) was heated in a sealed tube at 80° C. for 16 hours. The acidic pH was neutralized and then the solvent was evaporated and the crude mixture was purified by reverse phase chromatography (water/acetonitrile) to give the title compound (0.015 g, 25% of yield).
