Procedure

A solution of (15R,19R)-tert-butyl 15-(benzyloxycarbonylamino)-19-(decylcarbamoyloxy)-14,22-dioxo-4,7,10,21-tetraoxa-17-thia-13,23-diazatritriacontan-1-oate in MeOH (0.1 M) was stirred under nitrogen at room temperature. A small scoop (catalytic) of Pd/C was then added and stirred. A solution of ammonium formate (8 eq) in 9:1 MeOH/water was then added, the reaction vessel purged with nitrogen and heated to 40° C. for 4 hours. The reaction was then cooled to room temperature and diluted with EtOAc. The reaction mixture was filtered through celite then Na2SO4 and concentrated to afford the title compound as a light yellow oil. The concentrated material was used with no further purification.
