Reaction Steps

Methyl(2S)-2-(tert-butoxy)-2-[(22S)-5-ethenyl-17-fluoro-4,22,28-trimethyl-21,27-dioxa-1,7,34-triazahexacyclo[26.2.2.16,9.110,14.02,7.015,20]tetratriaconta-2,4,6(34),8,10(33),11,13,15(20),16,18-decaen-3-yl]acetate (30 mg, 0.044 mmol, 1.0 equiv) was dissolved in MeOH (439 μl). To this solution was added Pd/C (4.67 mg, 4.39 μmol, 0.1 equiv) and stirred under H2 balloon for 2 hours. The solid was filtered off through the celite. The filter was concentrated and the residue was used as is. LCMS (ESI, M+1): 686.4.
