Abstract:Tandospirone citrate was synthesized from 2-chloropyrimidine via a processes including N-hydrocarbylation, quaternization, nucleophilic and salify with a total yield of 65.2% and a chromatographic purity of 99.9%. The affecting factors including the acid-binding regent, the reaction temperature, solvent and the catalyst were investigated. The structures of the product and intermediates were characterized by 1H NMR and ESI-MS. The preparation process was simple in operation, low in raw material cost, and suitable for industrial production.
Key words:tandospirone citrate; improvement; N-hydrocarbylation; nucleophilic
