실험 절차

To a solution of 5-(benzyloxy)-6-(6-methylpyridin-3-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-indazole (1.44 g, 3.60 mmol) in EtOH (50 mL) and EtOAc (50 mL) is added Pd/C (500 mg, 10% wt) under N2. The resulting mixture is degassed by evacuation and backfilled with nitrogen. Then the reaction mixture is stirred at RT under H2 atmosphere overnight. The reaction mixture is filtered. The filtrate is concentrated to give the product (982 mg, 88.0% yield). MS (m/z): 310.1 (M+H).
