该中间体在本合成路线中的序号：(XXVIII)

The dehydration of peptide resin (XXVII) by means of EDC and CuCl in DMF/dichloromethane, followed by elimination of the Alloc protecting group with Pd(PPh3)4 and PhSiH3, gives the peptide resin (XXVIII). The cleavage of the protected peptide from the resin was performed with TFA in dichloromethane to yield peptide (XXIX), which is cyclized by means of DIEA and benzotriazol-1-yl-N-oxy-tris(pyrrolidino)phosphonium hexafluorophosphate (PyBOP) and finally deprotected with TFA in water to afford the target kahalalide F.
