実験手順

To a solution of (E)-N-(4-(difluoromethoxy)phenyl)-6-(2-(1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)vinyl)pyridazin-3-amine (0.14 g, 0.302 mmol) in ethyl acetate (5 mL) was added Pd—C (0.064 g, 0.604 mmol and the reaction mixture was stirred at room temperature under H2 for 3 h. The reaction mixture was filtered through pad of celite, washed with ethyl acetate, and the filtrate was concentrated to give N-(4-(difluoromethoxy)phenyl)-6-(2-(1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-5-yl)ethyl)pyridazin-3-amine as a yellow solid (0.13 g, 80%). LCMS (ES-API), m/z 466.6 (M+H).
