Abstract
The present disclosure provides a preparation method of setmelanotide by cyclization of a disulfide bond in a solid phase. By using different solvents or mixed solvents to carry out a cyclization reaction in a solid phase, the reaction concentration can be greatly increased in comparison with a cyclization reaction in a liquid phase, and the production of impurities can also be reduced, so that the effects of reducing the use of the solvents and increasing the production capacity are achieved.
