Procedure

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) and HBTU (1.2 eq) in DCM (0.06 M) was added DIEA (3.5 eq), followed by (1-aminocyclopropyl) methanol hydrochloride (1.2 eq). The reaction was stirred at room temperature for 2 hours. The crude mixture was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 30-50% EtOAc/Hex to give (R)-3-((R)-2-(((9H-fluoren-9-yl)methoxy)carbonylamino)-3-(1-(hydroxymethyl)cyclopropylamino)-3-oxopropylthio)propane-1,2-diyl didodecanoate.
