    • A piperazinyl-propyl-pyrazole derivative is provided to show excellent dopamine D4 affinity, inhibit the psychotic action of a mouse induced by apomorphine and exhibit relatively weak side effect at a mouse rotarod test, thereby being effectively used as a therapeutic and prophylactic agent of central nervous system diseases. A piperazinyl-propyl-pyrazole derivative is represented by a formula(1). In the formula(1), R^1 is C1-10 alkyl, or substituted or unsubstituted aryl or heteroaryl; one of R^2 or R^3 is H, and the other one of R^2 or and R^3 is C1-10 alkyl, benzyl, or substituted or unsubstituted aryl or heteroaryl; each R^4, R^5, R^6, and R^7 is independently H or C1-10 alkyl; each R^8, R^9, R^10, R^11 and R^12 is independently H, halogen, C1-10 alkyl, C1-C10 alkoxy, bis(substituted or unsubstituted aryl)alkylene, benzyl, nitro, hydroxy, cyano, amino, mono- or di-alkylamino, alkylcarbonylamino, aminosulfonyl, mono- or di-alkylaminosulfonyl, alkylcarbonyl, or alkyloxycarbonyl; and a dotted line is a single-bonded line or a double bond, wherein the aromaticity of a pyrazole-ring should be maintained, the aryl is phenyl, the heteroaryl is thiophenyl or pyridyl, and the substituted aryl or heteroaryl is an aryl or a heteroaryl substituted with one to three substituent(s) selected from the group consisting of halogen, nitro, C1-10 alkyl, C1-10 alkoxy, C1-10 haloalkyl, and C1-10 haloalkoxy. A method for preparing the piperazinyl-propyl-pyrazole derivative comprises a step of subjecting a pyrazole aldehyde derivative represented by a formula(2) and a piperazine derivative represented by a formula(3) to a reductive amination reaction. A pharmaceutical composition for treating central nervous system diseases comprise the compound of the formula(1).
