Reaction Steps
To a solution of diethyl (14R,18R)-14-(((9H-fluoren-9-yl)methoxy)carbonylamino)-18-(dodecyloxy)-13-oxo-3,6,9,20-tetraoxa-16-thia-12-azadotriacontylphosphonate (1 eq) was added 20% piperidine (50 eq) in acetonitrile. The resulting mixture was stirred at 25° C. until the deprotection completed. 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.
