, (2020/12/09)
The invention provides a synthesis method of a tedizolid phosphate intermediate 3-fluoro-4-bromoaniline. The synthesis method comprises the following steps: (1) performing reacting of a compound 1 with ammonia gas to obtain a compound 2; (2) performing reacting of the compound 2 with hydrobromic acid to obtain a compound 3; and (3) reducing a cyano group in the compound 3 into an amino group to obtain a compound 4. The raw material adopted by the method is cheap and easy to obtain, and the method is mild in reaction condition, simple in equipment requirement, high in safety index and suitablefor large-scale commercial production. The yield of the tedizolid phosphate intermediate 3-fluoro-4-bromoaniline prepared by the process provided by the invention is up to 56.61% or above, the purityis up to 99.70% or above, and the content of isomer impurities in the product is as low as 0.17% or below. The invention provides the cheap and easily available high-quality intermediate for commercial production of tedizolid phosphate bulk drugs, and a wide application prospect is achieved.

The present invention relates to compounds of formula (I), which have valuable pharmacological properties, in particular are activators of AMPK and which are therefore useful in the treatment of certain disorders that can be prevented or treated by activation of this receptor. The compounds are suitable for treatment and prevention of diseases which can be influenced by this receptor, such as metabolic diseases, in particular diabetes type 2.
Electrophilic bromination of meta-substituted anilines with N-bromosuccinimide: Regioselectivity and solvent effect

experimental part, p. 1305 - 1308 (2009/12/24)
N-Bromosuccinimide-mediated electrophilic aromatic bromination of a series of anilines substituted with an electron-with-drawing group in the meta position was investigated. The regioselectivity of the reaction is markedly dependent on the polarity of the solvent and the bromination reaction can be tuned by appropriate selection of the reaction medium.
