Tetrahydrofuran → 3-(1-Amino-2-naphthylamino)benzonitrile

Participants

Reaction Steps

3-(1-Nitro-2-naphthylamino)benzonitrile (1.16 g, 3.99 mmol) was hydrogenated in methanol (20 mL)/THF (40 mL) for 4 hours at room temperature using 10% palladium-carbon (220 mg) as a catalyst. After removal of the catalyst by filtration, the filtrate was concentrated to dryness. The residue was purified by silica gel column chromatography (chloroform/methanol=99/1), to give the titled compound as a yellow crystal (968 mg, yield 93%).
