실험 절차
A suspension of 3-[4-fluoro-3-(2-hydroxy-ethoxy)-phenyl]-1-trityl-5-nitro-1H-indazole 14AX (1.5 g) and catalytic amount of Pd on carbon (5 wt %, 300 mg) in 40 mL of methanol/toluene (1:1) was stirred under a hydrogen atmosphere for 1 d and filtered through Celite. The filtrate was concentrated to provide 3-[4-fluoro-3-(2-hydroxy-ethoxy)-phenyl]-1-trityl-1H-indazol-5-ylamine 15AX (1.4 g) as an off-white solid.
