Versuchsvorschrift
The compound 17-ethyl-1-hydroxy-12-[2'-(4"-amino-3"-isopropyloxycyclohexyl)-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(30 mg) is mixed with methyl formate (0.5 ml) and is stirred at 0° C. for 1 hr. The reaction mixture is allowed to warm to room temperature and then is stirred overnight. The excess methylformate is removed with nitrogen flow and the crude mixture is purified by preparative tlc on silica gel to give the title compound.
