A series of novel N-[1-(1-substituted 4-piperidinylmethyl)-4-piperidinyl]benzamides was prepared and its compounds were evaluated for their binding to 5-HT4 receptors and effects on gastrointestinal motility in conscious dogs. 4-Amino-N-[1-[l-(4aminobutyl)-4-piperidinylmethyi]-4-piperidinyl]-5-chloro-2-methoxybenzamide (15) was found to have a potent binding affinity for 5-HT4 receptors (IC50: 6.47 nM) and showed excellent colonic prokinetic activity.
