Abstract
259,977. Binz, A., and Rõth, C., (Assignees of Deutsche Gold-und Silber- Scheideanstalt vorm. Roessler). Oct. 17, 1925, [Convention date]. Addition to 251,578. 3-Iodopyridine is prepared by diazotizing 3- aminopyridine and reacting thereon with an iodizing agent, such as alkali iodide. The product possesses therapeutic properties. An example is given. 3-Aminopyridine is obtained by reduction of 3- nitropyridine with iron and acid.
