Methods The key intermediate 5-(1-piperazinyl)benzofuran-2-carboxamide was prepared from 4-(4-acetylpiperazine-1-yl)phenol by Duff reaction, substitution, cyclization, deprotection, and amidation. Vilazodone hydrochloride was synthesized from 5-(1-piperazinyl)benzofuran-2-carboxamide and 3-(4-chlorobutyryl)-1H-indole-5-carbonitrile by substitution and salification. Results The target compound vilazodone hydrochloride was synthesized and characterized by 1H-NMR and MS. The purity was 99.8%, and the total yield of this synthetic route was 22.5%. Conclusion The synthetic process with facile material and simple operation simplified method is applicable to industrial production."/>
