The N-3 position of a series of 3-phenoxypropyl piperidine benzimidazol-2-one analogues was optimised using the predictive power of a CoMFA model. The model was used to prioritise compounds for synthesis culminating in the triazole (+)-24. (+)-24 was found to be a high affinity, potent NOP agonist and demonstrated both antinociceptive and antiallodynic effects when administered iv to rodents.
