Abstract:
PURPOSE: A 1-phenyl-4-(1,2,3-triazole-1-ylalkyl)piperazine derivative and a pharmaceutically acceptable salt thereof are provided to have excellent affinity to dopamine D4 receptor. CONSTITUTION: A 1-phenyl-4-(1,2,3-triazole-1-ylalkyl)piperazine compound of chemical formula 1 with stereoselectivity or a pharmaceutically acceptable salt thereof is provided. The pharmaceutically acceptable salt is generated by a reaction with inorganic acids, organic acids, amino acids, sulfonic acids, alkali metals, or ammonium ions. A method for preparing the compound of chemical formula 1 comprises reductive amination of an aldehyde compound of chemical formula 2 and a phenylpiperazine compound of chemical formula 3.
