Procedure
A solution of (23R,27R)-23-(((9H-fluoren-9-yl)methoxy)carbonylamino)-1-(9H-fluoren-9-yl)-3,6,22-trioxo-5-(tritylthiomethyl)-2,11,14,17-tetraoxa-25-thia-4,7,21-triazaoctacosane-27,28-diyl didodecanoate in acetonitrile (0.1M) was stirred at room temperature. Piperidine (final conc. 20%) was then added and the reaction stirred for 30 minutes. After concentration, the product was purified by flash chromatography on an ISCO COMBIFLASH® system using an initial gradient of 0-100% EtOAc, then 0-10% MeOH/DCM to give (22R,26R)-4,22-diamino-5,21-dioxo-1,1,1-triphenyl-10,13,16-trioxa-2,24-dithia-6,20-diazaheptacosane-26,27-diyl didodecanoate.
