| Abstract: | For the preparation of 2-chloro-5-methylpyridine from 3-methylpyridine-N-oxide,an improvement was studied to increase the reaction conversion to 68% by adding AlCl3 as chlorinating additive. Compared with the original process,the method could increase the yield of 16%,effectively reducing the cost of production and possessing the potential application. |
