Procedure

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 (50 mg) was dissolved in pyridine (1.19 ml) containing mesyl chloride (12 μl). The solution was stirred for 1 hour in a dry ice-carbon tetrachloride bath under nitrogen atmosphere. The solution 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 4-formyl-6,9-dihydroxy-11-mesyl-14-oxa-1,11-diazatetracyclo[7.4.1.02,7.010,12 ]tetradeca-2,4,6-trien-8-ylmethyl carbamate (47 mg).
