Eight (1-benzyl-2(3H)-benzimidazolon-3-yl)acetic acid derivatives have been synthesized and tested for antinociceptive activity in this study. All compounds but one, at the oral dose of 100 mg/kg were comparable with aspirin. Ethyl (1-benzyl-2(3H)-benzimidazolon-3-yl)acetate (3), 4-[(1-benzyl-2(3H)-benzimidazolon-3-yl)acetyl]morpholine (6a) and 1-[(1-benzyl-2(3H)-benzimidazolon-3-yl)acetyl]pyrrolidine (6b) have shown more potent antinociceptive activity than others.
