Procedure

To a solution of 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) in methanol (5 ml) were added O-methylhydroxylamine hydrochloride (105 mg) and sodium bicarbonate (106 mg). The mixture was stirred for 1.5 hours 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 (4:1, v/v) to afford 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 (80 mg).
