실험 절차

4-Formyl-6,9-dihydroxy-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-8-ylmethyl carbamate (100 mg) was dissolved in 1N aqueous sodium hydroxide (10 ml), and the pale yellow solution was allowed to stand at room temperature for 72 hours. The reaction mixture was neutralized with 1N hydrochloric acid and then lyophilized. The residue was subjected to a silica gel column chromatography and elution was carried out with a mixture of methanol and chloroform (1:9, v/v). The desired fractions were combined and then evaporated to dryness in vacuo to give 4-hydroxymethyl-8-methylene-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-triene-6,9-diol (21 mg).
