Procedure

6,9-Dihydroxy-8-hydroxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-triene-4-carbaldehyde (4 mg) was dissolved in pyridine (1 ml). To this solution was added acetic anhydride (50 μl) and the mixture was allowed to stand at room temperature overnight. The reaction mixture was evaporated to dryness in vacuo and the residual oil was subjected to preparative thin layer chromatography, which was developed with a mixture of methanol and chloroform (5:95, v/v) to yield 8-acetoxymethyl-11-acetyl-4-formyl-9-hydroxy-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-6-yl acetate (1.5 mg).
