Procedure

To a solution of diethyl(12R,16R)-12-(((9H-fluoren-9-yl)methoxy)carbonylamino)-16-(dodecanoyloxy)-1,1-difluoro-11,19-dioxo-4,7,18-trioxa-14-thia-10-azatriacontylphosphonate (1 eq) was added 20% piperidine (50 eq) in acetonitrile The resulting mixture was stirred at 25° C. until the smarting material disappeared. To the mixture was added toluene and then concentrated en vaccuo. The crude mixture was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 100% EtOAc then 0-10% MeOH/DCM to give the product as a colorless oil.
