Procedure

To a solution of 17-ethyl-1,14-dihydroxy-12-[2'-(4"-(1-t-butyldimethylsilyloxyethylindol-6-yl)oxy-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. (150 mg) in CH2Cl2 (4 mL.) at rt was added a solution of p-toluene sulfonic acid (20 mg.) in CH3OH (4 mL.). The reaction mixture was stirred for 2 hr., quenched with saturated NaHCO3, then extracted with CH2Cl2. The extracts were combined, dried over Na2SO4, filtered and concentrated in vacuo. The product was purified by preparative TLC on silica gel (2:1, hexane/acetone) to give 55 mg of the title compound.
