Procedure
A solution of 31 mg of (4R,9S)-16-[dimethyl-(1,1,2-trimethylpropyl)-silanyloxy]-9-hydroxymethyl-14-methoxy-13-methyl-4-(3-methyl-1,2,4-oxadiazol-5-yl)-6-thioxo-1,3,4,5,6,7,8,9,10,12-decahydro-11,2,5-benzoxathiaazacyclotetradecin-12-one and 11.5 mg of methanesulfonyl chloride in 0.2 ml of pyridine was stirred at 20° C. for 3 h. The solution was partitioned between dichloromethane and 1M aqueous oxalic acid. The organic layer was washed with brine, dried over sodium sulfate and evaporated in vacuo to yield 46 mg of (4R,9R)-16-[dimethyl-(1,1,2-trimethyl-propyl)-silanyloxy]-14-methoxy-13-methyl-4-(3-methyl-1,2,4-oxadiazol-5-yl)-9-(methylsulfonyloxymethyl)-6-thioxo-1,3,4,5,6,7,8,9,10,12-decahydro-11,2,5-benzoxathiaazacyclotetradecin-12-one as an amorphous solid.
