To a solution of 1-(6-(6-(1-methyl-1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)azetidin-3-one (1.1 g) in DCM (10 mL) at 20° C. was added nitromethane (1 mL) and triethylamine (0.5 mL). The mixture was stirred at ambient temperature for 2 hours. It was concentrated under reduced pressure to afford a white solid. The crude product (1.3 g), 1-(6-(6-(1-methyl-1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)-3-(nitromethyl)azetidin-3-ol, was used for next step without further purification. MS (ESI) m/z: 407 [M+H]+.
