Preparation method of pyridine derivative (by machine translation)

To the method, piperidine-4-one hydrochloride is used as a raw material, and a series of pyridine derivatives are obtained through halogenation reaction and elimination reaction. The reaction is eliminated by reacting piperidine-4-one hydrochloride with a specific amount of the 3,5 - halogenating agent in a halogenation 3, 3, 5 - reaction with a halogen-3, 3, 5, 5 - based reaction, followed by reaction with a pyridine derivative of a hydroxyl group, an amino group 4 - or a dimethylamino group, respectively, by eliminating the reaction with a different kind of basic agent. The method is simple and convenient to operate, mild in condition, short in technological process, low in waste water yield, environment-friendly, low in cost and beneficial to green industrial production of the pyridine derivative.

Convenient chlorination of some special aromatic compounds using N-chlorosuccinimide

Some chlorinated aromatic compounds, including indole, benzofuran, carbazole, pyridine and aniline derivatives, are difficult to obtain through convenient chlorination. We herein report their efficient synthesis through chlorination with N-chlorosuccinimide (NCS). Optimization of the reaction conditions, including the temperature and the choice of solvent, was also investigated. This approach, which is characterized by a facile procedure, comparatively high yields and environmentally friendly features, provides a straightforward and inexpensive route to several chlorinated aromatic compounds.
