摘要： The present invention is related to a method of producing a peptide, characterized in contacting a reaction mixture with a base after a condensation reaction to hydrolyze while a basic condition is maintained until a ratio of a remaining unreacted active ester of an acid component is decreased to 1% or less in a liquid phase peptide synthesis method. According to the invention, a target peptide of high purity can be simply and efficiently produced by a continuous liquid phase synthesis method. Further, the present invention is related to a method of producing a peptide, characterized in using an amide-type solvent immiscible with water in a liquid phase peptide synthesis method. According to the invention, various peptides can be produced by the liquid phase synthesis method without being restricted by the amino acid sequence of the target peptide.
