  • Publication number: 20230043220
    Abstract: The present invention relates to a method for preparing etelcalcetide hydrochloride (etelcalcetide HCL). A first peptide is de-protected and cleaved from a solid support by a first solution system, for obtaining a second peptide, followed by coupling an activated L-Cys-OH to the second peptide in the second solution system for forming a TFA salt of etelcalcetide that is not or hardly dissolved in the second solution system. After purification by column chromatography, the TFA salt of etelcalcetide can be converted to etelcalcetide HCL using a third solution system that excludes hydrogen chloride during a real-time monitoring salt exchange step. The present method provides a simplified process and the etelcalcetide HCL with high purity and yield, for being advantageously applied in mass production of etelcalcetide HCL.
