Abstract
A new and improved synthetic route to vortioxetine hydrobromide is established on a hectogram scale through three simple steps in 63% yield and with 99% purity (HPLC). The key step is the cyclization of the piperazine ring in the final step. Purification methods for the intermediates involved in the route are given.
