실험 절차
[4-nitro-2-(2,2,2-trifluoroethoxy)phenyl](pyridin-2-yl)methanol (4.5 g) was dissolved in ethanol (150 ml), and the solution was reduced by catalytic hydrogenation overnight with 10% palladium-carbon of 50% hydration (0.25 g). The catalyst was removed, and the solvent of the filtrate was distilled off. The residue was purified by silica gel column chromatography (elution solvent: ethyl acetate), to give [4-amino-2-(2,2,2-trifluoroethoxy)phenyl](pyridin-2-yl)methanol (3.6 g) as yellow crystals.
