    • PURPOSE: Provided are novel isoxazolylalkylpiperazine derivatives having selective activity for dopamine D3 and D4 receptor represented by the formula(1) and their manufacturing method by reductive amination in the presence of a reductant. The derivatives and their pharmaceutically acceptable salts are useful in the treatment of mental illness. CONSTITUTION: The novel isoxazolylalkylpiperazine derivative of the formula(1) is prepared by reacting amine compound represented by the chemical formula(2) with aldehyde compound shown in the chemical formula(3) in the presence of a reductant selected from NaBH(OAc)3, NaBH3CN and NaBH4 in a reductive amination reaction. In the formulae, R1,R2,R3,R4, and R5 are same or different each other and are hydrogen atom, halogen atom, C1-C6 alkyl, C1-C6 alkoxy, C2-C6 alkenyl, hydroxy, hydroxymethyl, aryl, heteroaryl, amino group, C1-C6 alkylamino, carbonyl, C3-C8 cycloalkyl, or C3-C8 heterocyclic group; R6 is hydrogen atom, halogen atom, alkyl, C1-C6 alkoxy, aryl, pyridyl, heterocyclic, pyrimidyl group; X is CH or nitrogen atom; and n is 3 or 4.
