To a solution of the FR-900506 substance (10.4 mg) in dichloromethane (0.2 ml) were added Dvridine (0.1 ml) and acetic anhydride (0.05 ml) at room temperature, and the mixture was stirred for 5 hours. The solvent was removed from the reaction mixture under reduced pressure. The residue was subjected to silica gel thin layer chromatography (developing solvent: diethyl ether and dichloromethane, 1:2 v/v) to give 12-[2-(4-acetoxy-3-methoxycyclohexyl)-1-methylvinyl]-17-allyl-1,14-dihydroxy-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.04,9 ]octacos-18-ene-2,3,10,16-tetraone (6.0 mg).
