Adding a certain compound to certain chemical reactions, such as: 69045-78-9, 2-Chloro-5-(trichloromethyl)pyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 69045-78-9, blongs to pyridine-derivatives compound. category: pyridine-derivatives
Example 1 In a 120 cc autoclave equipped with a magnetic stirrer, 2-chloro-5-trichloromethylpyridine (11.5 g), Raney nickel (1.15 g) and a 70% aqueous solution of ethylamine (32.2 g) were charged. Hydrogen gas was introduced into the autoclave to a pressure of 10 Kg/cm2, and an internal temperature was raised to 45 C. At the same temperature, the hydrogen gas was supplied under a hydrogen pressure of 5 to 12.5 Kg/cm2. The absorption of hydrogen ceased after 70 minutes from the start of hydrogen supply. After completion of reaction, the autoclave was cooled to room temperature, and the catalyst was filtrated off from the reaction mixture. The filtrate was adjusted to pH 12.9 with a 48% aqueous solution of sodium hydroxide and the filtrate was concentrated. Water was added to the concentrate, and the product was extracted with toluene twice. After phase separation, the toluene layer was concentrated to obtain a concentrate (8.0 g) containing 2-chloro-5-ethylaminomethylpyridine, which was analyzed by gas chromatography to find that a yield of 2-chloro-5-ethylaminomethylpyridine was 77%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,69045-78-9, its application will become more common.
