  The present invention has an object of providing a peptide synthesis method using a carrier capable of reversibly repeating the dissolved state and the insolubilized state, wherein the problem of an amino acid active species existing in the reaction system in de-protection reaction can be easily solved. The present invention provides a peptide synthesis method comprising the following steps: a step of condensing an N-Fmoc protected amino acid with a peptide having a C-terminal protected with a carrier which is crystallized according to a change of a composition of a dissolving solvent, in the presence of a condensing agent, to obtain an N-Fmoc-C-carrier protected peptide, a step of adding an alkylamine having 1 to 14 carbon atoms or hydroxyl amine to the reaction system, a step of de-protecting the N-terminal, and a step of changing the composition of the solvent dissolving the C-carrier protected peptide, to crystallize and separate the peptide.

  本发明的目的是提供一种肽合成方法，使用能够可逆地重复溶解状态和不溶解状态的载体，从而可以轻松解决去保护反应中存在的氨基酸活性物种的问题。本发明提供一种肽合成方法，包括以下步骤：将N-Fmoc保护的氨基酸与具有C末端保护的肽在存在缩合剂的情况下与根据溶解溶剂的组成变化结晶的载体进行缩合，以获得N-Fmoc-C-载体保护的肽，向反应体系中加入具有1至14个碳原子的烷基胺或羟胺，去保护N末端，改变溶解C-载体保护的肽的溶剂组成的步骤，结晶并分离肽。
