Procedure

To a solution of (R)-2-(benzyloxycarbonylamino)-3-((R)-2,3-bis(decylcarbamoyloxy)propylthio) propanoic acid (15, 1 eq) and HBTU (1.2 eq) in DCM (0.06 M) was added DIEA (2.4 eq), followed by diethyl 2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)ethylphosphonate (1.2 eq, from example 18, step 4). The reaction was stirred at room temperature for 4 hours. The crude mixture was purified by flash chromatography on a COMBIFLASH® system (ISCO) using a gradient of 0-10% MeOH/DCM to afford the title compound as a clear viscous oil.
