To a solution of 17-ethyl-1,14-dihydroxy-12-[2'-(4"-(m-carboxybenzyloxy)-3"-methoxycyclohexyl)-1'-methylvinyl]-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 (7 mg) in methylene chloride: methanol (2:1, 0.75 mL) at 0° C. was added a methylene chloride solution of trimethylsilyldiazomethane (10% by weight) until a yellow colored persisted. The mixture was then warmed to room temperature, concentrated in vacuo, and purified by flash chromatography on silica gel (acetone:hexane (1:2)) to give the title compound (5.5 mg).
