Versuchsvorschrift

To a solution of 4-(2-tetrahydropyranyloxymethyl)nitrobenzene (59.7 g, 0.256 mol) in ethanol (EtOH) (300 ml) was added under nitrogen atmosphere at room temperature 10% Pd/C (5.97 g), and catalytic hydrogenation was carried out. The mixture was stirred at room temperature for 24 hours. After the reaction completed, the catalyst was filtered off, and the organic layer was concentrated under reduced pressure. The residue was purified with silica gel column chromatography to give 4-(2-tetrahydropyranyloxymethyl)aniline (39.7 g, 76%) as syrup.
