Reaction Steps
To a solution of (5R,9R)-9-dodecanamido-1-(9H-fluoren-9-yl)-3-oxo-2,11-dioxa-7-thia-4-azaheptacosane-5-carboxylic acid (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 hr. The crude mixture was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 30-50% EtOAc/Hex to give (9H-fluoren-9-yl)methyl (R)-3-((R)-2-dodecanamido-3-(hexadecyloxy)propylthio)-1-(1-(hydroxymethyl)cyclopropylamino)-1-oxopropan-2-ylcarbamate.
