실험 절차

In a reactor, 4 mg of 18-crown-6 ether and then 230 mg of NaNH2 are successively introduced into a suspension of 100 mg of 3-methoxyacenaphthoquinone in 1 ml of DMSO. The mixture is stirred for 30 minutes at ambient temperature. Water (2 ml) is then added, followed by 2N HCl solution (3 ml). After two extractions with ethyl acetate, the solvents are dried over Na2SO4 and then evaporated off to yield the title product in the form of a yellow solid in a yield of 88% and with a chemical purity of more than 94%.
