実験手順

A solution of (14R,18R)-14-amino-18-(dodecanoyloxy)-13,21-dioxo-3,6,9,20-tetraoxa-16-thia-12-azadotriacontylphosphonic acid diethyl ester (1 eq, from example 18, step 6) in DCM (0.1 M) was cooled in an ice bath. Pyridine (1.2 eq) was added followed by palmitoyl chloride (1.1 eq). The reaction mixture was stirred for 10 minutes then warmed up to room temperature, and stirred for 2 hours. The reaction mixture was diluted with DCM, washed with saturated aqueous NH4Cl. The aqueous phase was back extracted with DCM. The combined organic phases were washed with brine, dried over anhydrous Na2SO4 and concentrated en vaccuo. The resulting crude was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-10% MeOH/DCM to give the title product as a white solid.
