Objective To study the synthetic technology of vilazodone hydrochloride. Methods 5-Cyanoindole was used as starting material to synthesize vilazodone by Friedel-Craft reaction, reduction reaction, sulfonylation reaction, and condensation reaction. Then vilazodone hydrochloride was synthesized by reacting with hydrochloric acid. Results The target compound was synthesized and characterized by ¹H-NMR and MS. The total yield of vilazodone hydrochloride with the purity of 99.66% was 47.89%. Conclusion The synthetic route of vilazodone hydrochloride has the advantages of reasonable design and simple operation with high yield and purity, and is suitable for industrial production.
