Procedure
11-Acetyl-4-formyl-8-carbamoyloxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-6,9-diyl diacetate (20 mg) was dissolved in ethyl acetate (5 ml) and the solution was subjected to catalytic reduction for 2 hours using 10% palladium on carbon under atmospheric pressure at room temperature. The reaction mixture was filtered and the filtrate was evaporated to dryness in vacuo. 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 11-acetyl-8-carbamoyloxymethyl-4-hydroxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-6,9-diyl diacetate (17 mg).
