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 tert-butyl 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)propanoate (1.2 eq). 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 0-100% EtOAc/Hex to afford the title compound as an off-white solid.
