Abstract:Using(R)-(-)-mandelic acid as the starting material, mirabegron was obtained from a 8-step reaction process including condensation and reduction reactions. The optimal conditions of each step were investigated. A total yield of 20.9% was obtained. All reaction conditions were mild, the operations were simple, and the costs of the materials were relatively low. This process for the preparation of mirabegron was suitable for industrial production.
Key words:overactive bladder; Mirabegron; synthesis
