Reaction Steps
A solution of (12R,16R)-12-(((9H-fluoren-9-yl)methoxy)carbonylamino)-16-dodecanamido-1,1-difluoro-11-oxo-4,7,18-trioxa-14-thia-10-azatriacontylphosphonic acid diethyl ester in acetonitrile (0.1M) was stirred at room temperature. Piperidine (final conc. 20%) was then added and the reaction stirred for 30 minutes. After concentration, the crude material was by flash chromatography on a COMBIFLASH® system (ISCO) using a gradient of 0-100% EtOAc/Hex, then 0-10% MeOH/DCM to give the title compound as an off-white solid.
