Reaction Steps
To a solution of (5R,9R)-9-(dodecanoyloxy)-1-(9H-fluoren-9-yl)-3,12-dioxo-2,11-dioxa-7-thia-4-azatricosane-5-carboxylic acid (6, 1 eq) in DCM (0.1 M) was added diethyl 4-amino-1,1-difluorobutylphosphonate hydrochloride (1.1 eq), DIEA (3.5 eq) and HBTU (1.1 eq). The reaction mixture was then stirred at room temperature for 2 hours. The mixture was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 30-70% EtOAc/Hex to give the product.
