Reaction Steps

To a solution of 140 mg of (4R,9R)-16-[dimethyl-(1,1,2-trimethyl-propyl)-silanyloxy]-9-hydroxymethyl-14-methoxy-13-methyl-4-(3-methyl-1,2,4-oxadiazol-5-yl)-1,3,4,5,6,7,8,9,10,12-decahydro-11,2,5-benzoxathiaazacyclotetradecin-6,12-dione and 121 mg of triphenyl-phosphine in 2 ml of tetrahydrofuran were added at 0° C. 80 mg of diethyl azodicarboxylate and 127 mg of diphenylphosphoryl azide. The mixture was stirred at 0° C. for 35 min and then evaporated in vacuo. The residue was chromatographed on silica gel using ethyl acetate/hexane (1:1, v/v) as eluent, to yield (4R,9R)-9-azidomethyl-16-[dimethyl-(1,1,2 -trimethyl-propyl)-silanyloxy]-14-methoxy-13-methyl -4-(3-methyl-1,2,4-oxadiazol-5-yl)-1,3,4,5, 6,7,8,9,10,12-decahydro-11,2,5-benzoxathiaazacyclotetradecin -6,12-dione as a foam
