  The present invention provides a method for producing a peptide, characterized in that it comprises converting an —SH group of a peptide comprising an amino acid residue having the —SH group to an —OH group, wherein said method comprises the following steps (a) to (c): (a) allowing an —SH group in a peptide to react with a methylating agent to convert the —SH group to an -SMe group; (b) allowing the -SMe group obtained in the step (a) to react with a cyanizing agent to produce a reaction intermediate; and (c) converting the reaction intermediate obtained in the step (b) to a peptide comprising an amino acid residue having an —OH group under more basic conditions than the conditions in the step (b).

  本发明提供了一种生产肽的方法，其特征在于包括将含有—SH基团的氨基酸残基的肽的—SH基团转化为—OH基团，其中所述方法包括以下步骤(a)至(c)：(a)使肽中的—SH基团与甲基化剂反应，将—SH基团转化为-SMe基团；(b)使步骤(a)中获得的-SMe基团与氰化剂反应，产生反应中间体；(c)在比步骤(b)中更基性的条件下将步骤(b)获得的反应中间体转化为含有—OH基团的氨基酸残基的肽。
