Participants

Reaction Steps

To a solution of 6,9-dihydroxy-8-hydroxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-triene-4-carbaldehyde (98 mg) in methanol (3 ml) was added acetic anhydride (40 μl). The mixture was stirred for 1 hour at ambient temperature and evaporated in vacuo. The residue was subjected to preparative thin layer chromatography, which was developed with a mixture of chloroform and methanol (10:1, v/v) to afford 11-acetyl-6,9-dihydroxy-8-hydroxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-triene-4-carbaldehyde (71 mg).
