실험 절차

To a stirred solution of 17-ethyl-20-fluoro-1,14-dihydroxy-12-[2'-(4"-(6'"-tert-butyldimethylsilyloxynaphth-2-yloxy)-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 (73 mg, 0.07 mmol) in CH2Cl2 (2 mL) was added a solution of p-toluenesulfonic acid in methanol (2 mL, 10% solution). The flask is capped and the mixture stirred 4 hours. The reaction is quenched with saturated aqueous NaHCO3 and extracted 4× with CH2Cl2. The organic extracts are combined and dried over anhydrous Na2SO4. The mixture is filtered and concentrated in vacuo. The product is isolated by preparative TLC on silica gel to afford the title compound.
