functionality transformations, this process successfully prevented the tosyl group from encountering any alkoxides, which would inevitably lead to the generation of alkyl tosylate and indole N-alkylated vilazodone byproducts. In addition, this manufacturing process has also been demonstrated on a kilogram scale, delivering 1.05 kg of vilazodone hydrochloride with an overall yield of 71% (calculated from ethyl
