実験手順
A solution of 2-chloro-1,4-naphthoquinone (10.3 g) in tetrahydrofuran (100 mL) was treated with a suspension of sodium methoxide (3.20 g) in tetrahydrofuran (25 mL) at room temperature. After stirring overnight, the mixture was evaporated, and the residue was taken up in ether. The organic layer was washed with brine, dried, filtered and evaporated. Chromatography over silica gel gave 2-methoxy-1,4-naphthoquinone, m.p. 182°-183° C.
