2-Methoxy-1,4-Naphthoquinone → 2-Methoxynaphthalene-1,4-diol

참여 물질

반응 단계

A solution of 2-methoxy-1,4-naphthoquinone (20.0 g) in tetrahydrofuran (150 mL) was hydrogenated at atmospheric pressure over Pd-C (10%, 0.5 g) until the calculated amount of hydrogen was absorbed, approximately 4 hours. Filtering off the catalyst under an atmosphere of nitrogen gave a solution of the desired product, which was used as such without isolation of the product as the starting material in Examples 1, 2 and 3, infra. Alternatively, the solvent is removed under reduced pressure and the residue recrystallized from diethyl ether/pentane, affording 2-methoxy-1,4-dihydroxynaphthalene.
