実験手順

To a solution of 404.5 mg of 17-ethyl-1,14,20-trihydroxy-12-[2'-(4"-hydroxy-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, 64.8 mg 4-dimethylaminopyridine, 87.1 μl of diisopropyl ethyl amine and 4 ml methylene chloride stirred magnetically at 0° C. was added 113.2 mg o-nitrophenylsulfonyl chloride in 2 ml methylene chloride. At 19 hours the mixture was evaporated and purified by thin layer chromatography on silica gel using hexane/acetone mixtures (60/40 and 50/50) as eluent. The faster moving compound, 155 mg, was repurified on silica gel preparative thin layer chromatography using ethyl acetate as eluent. The slower moving compound, 69.8 mg, was identified as 17-ethyl-1,20-dihydroxy-12-[2'-(4"-hydroxy-3"-methoxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.04,9 ]octacos-14,18-diene-2,3,10,16-tetraone.
