Abstract
288,628. Schering-Kahlbaum Akt.- Ges., (Assignees of Rõth, C.). April 14, 1927, [Convention date]. 2-Hydroxypyridines and their derivatives are obtained by treating a 2-halogenpyridine which has no hydrolysable group in the 5-position or a derivative thereof with an alkaline or acid hydrolyzing agent, in the presence or absence of a solvent or diluent. Suitable starting materials are 2-halogenpyridines which may contain 3- or 5- arsinic acid groups, or nitro groups, or further halogen groups. The products possess therapeutic properties. Examples are given of the treatment of 2-chloropyridine with caustic potash to give 2-hydroxypyridine, and of both the hydrochloric acid and caustic soda saponification of 2- chloro-5-nitropyridine to from 2-bydroxy-5-nitropyridine. Specification 288,629 is referred to.
