Development of a practical and scalable synthesis of anti-HBV drug Y101
2014
Abstract The process research and development of a practical and scalable synthetic method towards Anti-HBV Drug N -[ N -benzoyl- O -(2-dimethylaminoethyl)- l -tyrosyl]- l -phenylalaninol ( Y101 ) was described. Initial synthetic routes of Y101 in milligram quantities were unsuitable for large-scale synthesis to provide bulk material. As part of the collaboration between Medicinal Chemistry and Research active pharmaceutical ingredient (API), a fit for purpose route for the kilo scale synthesis of Y101 was developed. In contrast, the improved route described here did not require purification by column chromatography for all steps, and the formation of impurities was effectively suppressed. This highly efficient and scalable process was successfully demonstrated in the large-scale synthesis of Y101 .
