ines and their binding affinities for dopamine D3 and D4 receptors. The synthesis of isoxazolylpyrrolidinylpiperazine derivatives is shown in Schemes 1, 2 and 3. The key synthetic strategy to these compounds involved couplingbetween two buildingblocks 2 and 3 using reductive amination reaction. Preparation of buildingblock 2 is described in Scheme 2. Protection of the amino group of pyrrolidin-2-ylmethanol
