How is Abrocitinib Manufactured?
The synthesis of abrocitinib involves a multi-step process. One described route begins with the preparation of 3-(difluoromethyl)-1H-pyrazole-4-carboxamide. This intermediate is then reacted with 6-fluoro-2-(methylamino)isonicotinic acid in the presence of a coupling agent and a base. Further steps involve cyclization and purification to yield abrocitinib [1].
