The present invention provides a process for the manufacture of peptidomimetic drug icatibant with high yield and purity by fragment condensation on the solid phase. In particular, it describes a convergent synthesis by condensation of a protected C-terminal fragment bound to a solid support and a protected N-terminal fragment, followed by cleavage from the support and resulting in a crude peptide of high purity, which is further purified to obtain pure icatibant in high yield. The invention further provides intermediates useful in the manufacturing process.
A method for the preparation of icatibant, wherein the method comprises the step of coupling a first resin-bound peptide fragment A characterized by the sequence Thi-Ser-(D)Tic-Oic-Arg, with a second peptide fragment B comprising a C-terminal glycine, optionally followed by one or more steps of elongation of the resulting peptide to complete the icatibant sequence.
