Reaction Steps

A mixture of (5R,9R)-tert-butyl 9-azido-1-(9H-fluoren-9-yl)-3-oxo-2,11-dioxa-7-thia-4-azaheptacosane-5-carboxylate (1.0 eq), Pd(OH)2 (0.5 eq), dodecanoyl chloride (2.4 eq), and DIEA (4.8 eq) in EtOAc (0.01 M) was stirred under H2 (1 atm) at 25° C. overnight. The reaction was filtered and washed with DCM. The filtrate was concentrated en vaccuo. The resulting crude was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-20% EtOAc/Hex to give (5R,9R)-tert-butyl 9-dodecanamido-1-(9H-fluoren-9-yl)-3-oxo-2,11-dioxa-7-thia-4-azaheptacosane-5-carboxylate as a colorless oil.
