2-Alkoxy-4-amino-N-[(4-benzyl-2-morpholinyl)methyl]-5-chlorobenzamides had been identified as the interesting members of a series of selective and potent gastroprokinetic agents. A new series of 2-amino- and 2-(substituted amino)-N-[(4-benzyl-2-morpholinyl)methyl]benzamides (13-35) has been synthesized and these compounds were examined to determine whether they have advantages over the 2-morpholinyl benzamides 1 with a 2-alkoxy group.The gastroprokinetic activity was generally reduced, but several compounds showed relatively potent activity, comparable to that of the standard agent, metoclopramide. N-[(4-Benzyl-2-morpholinyl)methyl]-4-chloro-2-[(4-chlorobenzoyl)amino]benzamide (32) showed the most potent activity in this series.
