TDM-621 Method of preparing TDM-621

摘要

The present invention relates to a method for preparing TDM-621. According to the present invention, TDM-621 having high purity and high yield can be prepared with a relatively simple method by solving problems according to an existing solid synthesis method. Accordingly, a novel method for preparing TDM-621 is suitable for commercial mass production. To this end, the method comprises performing a coupling reaction of peptides through a solution-phase synthesis method, and obtaining and deprotecting a peptide.
