Procedure
(2-methoxy-4-nitrophenyl)(pyridin-2-yl)methanol (0.5 g) was dissolved in ethyl acetate (25 ml), and the solution was reduced by catalytic hydrogenation overnight with 10% palladium-carbon of 50% hydration (50 mg). The catalyst was removed, and the solvent of the filtrate was distilled off to give (4-amino-2-methoxyphenyl)(pyridin-2-yl)methanol (0.4 g) as colorless crystals.
