title: 3-(2,5-Dihydro-1H-pyrrol-2-ylmethoxy)pyridines: synthesis and analgesic activity.
abstract: We disclose an efficient procedure for the preparation of ethers of 2-substituted 2-hydroxymethylpyrroline and of 2-aminomethyl-3-pyrrolines, involving, as a key step, formation and nucleophilic ring opening of a cyclic sulfamidate. Several new analogs of epibatidine (1) and tebanicline (ABT-594, 2) were prepared and tested for analgesic activity in the mouse formalin model.
