Versuchsvorschrift

To a solution of 17-ethyl-1-hydroxy-12-[2'-(4"-azido-3"-propyloxycyclohexyl)-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 (46 mg) in 10% aqueous benzene (900 μl) was added triphenylphosphine (29 mg) and the mixture heated to 70° C. with stirring. After 6.5 hours, the stir bar was removed and the reaction cooled to room temperature. The mixture was concentrated to 10% volume in vacuo and applied directly to a column of silica gel for purification by flash chromatography (ethyl acetate: hexane (1:1)+1% methanol then 2% ammonium hydroxide, 5% methanol in methylene chloride) to give the title compound (37 mg).
