4-Amino-N-arylpiperidines serve as effective bioisosteres for N-arylpiperazines in the series of dihydropyridine NPY1 receptor antagonists. These were prepared by a ZnCl2-mediated reductive amination reaction between elaborated primary amines, 2 or 5, and 4-arylpiperidones. (C) 2004 Elsevier Ltd. All rights reserved.
