실험 절차

11-Benzyloxycarbonyl-6,9-dihydroxy-4-dimethoxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-8-ylmethyl carbamate (15 mg) was dissolved in a mixture of pyridine (1.0 ml) and acetic anhydride (0.5 ml). The solution was stirred for 1 day at room temperature. To the solution was added 4-dimethylaminopyridine (catalytic amount) and the mixture was stirred for 12 hours at room temperature. The reaction mixture was evaporated in vacuo, and the residue was subjected to preparative thin layer chromatography. Development was carried out with a mixture of chloroform and methanol to afford 11-benzyloxycarbonyl-8-carbamoyloxymethyl-4-dimethoxymethyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-6,9-diyl diacetate (17 mg).
