실험 절차

To a solution of 6-[2-ethyl-5-fluoro-4-(2-trimethylsilanyl-ethoxymethoxy)-phenyl]-1-(tetrahydro-pyran-2-yl)-1H-indazole-3-carbonitrile (Preparation 6, 37.42 g, 75.6 mmol) in methanol (700 mL) was added sodium methoxide (12.21 g, 226.8 mmol) and the reaction mixture was then stirred at room temperature for 18 hours. The solvent was removed in vacuo and the residue was partitioned between EtOAc (1 L) and water (500 mL). The organic layer was washed with water (500 mL), dried over MgSO4 and concentrated in vacuo to give the title compound as a gum (37.26 g) in a 94% yield.
