Procedure

A solution of 32 mg of 17-ethyl-1-hydroxy-12-[2'-(4"-amino-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 in dry methylene chloride (0.4 ml) is cooled to 0° C. To this solution is added triethylamine (10 μl) followed by a solution of cyclopropane carbonyl chloride (5 mg) in methylene chloride (0.1 ml). The reaction mixture is stirred at 0° C. for 30 min. The reaction mixture is purified by preparative tlc on silica gel to give the title compound.
