To a solution of trimethyl-[2-[[6-(5-vinyl-3-pyridyl)pyrazolo[4,3-c]pyridin-1-yl]methoxy]ethyl]silane (543.4 mg) in Ethanol (50 mL) in a 250 mL round bottom flask was added Pearlman's catalyst (0.1850 mmol; 129.9 mg). The flask was vacuumed and connected with a balloon of Hydrogen. The mixture was stirred at room temperature overnight. The mixture was filtered through Celite. The filtrate was concentrated. The residue was purified on silica eluted with 0 to 5% MeOH in DCM to afford 2-[[6-(5-ethyl-3-pyridyl)pyrazolo[4,3-c]pyridin-1-yl]methoxy]ethyl-trimethyl-silane (87 mg, 27%).
