実験手順

Methyl 9-(1,3-benzodioxole-5-yl)-8-methyl-naphtho[1,2-d]-1,3-dioxole-7-carboxylate was dissolved in a mixture of THF (6 ml) and methanol (3 ml). After addition of 1N NaOH (3 ml), the mixture was stirred for 4 days. 1N HCl was added to the reaction mixture, followed by addition of water. The resulting precipitate was collected by filtration to yield the title compound (264 mg). Some portions of the compound was recrystalized from methanol-chloroform to be used for elemental and instrumental analysis.
