Procedure

6,9-Dihydroxy-4-methoxyiminomethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-8-ylmethyl carbamate (55 mg) was dissolved in a mixture of pyridine (3 ml) and acetic anhydride (1.5 ml) and stirred for 12 hours at ambient temperature. The mixture was evaporated in vacuo and subjected to preparative thin layer chromatography, which was developed with a mixture of chloroform and methanol (20:1, v/v) to afford 11-acetyl-8-carbamoyloxymethyl-4-methoxyiminomethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-6,9-diyl diacetate (62 mg).
