It is an object of the present invention to provide a novel method for producing a peptide thioester. In the present invention, general peptide synthesis is performed on a solid-phase resin, carboxylic acid obtained after cutout is allowed to react with p-toluenesulfonyl isocyanate, and then the reaction product is alkylated, and is reacted with thiol. Thus, peptide thioester is simply synthesized under mild conditions.
