Application of 934279-60-4, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 934279-60-4, name is 2-Chloro-5-(trifluoromethyl)nicotinaldehyde. A new synthetic method of this compound is introduced below.
To a solution of 2-chloro-5-(trifluoromethyl)pyridine-3-carbaldehyde of step 1-1 in ethanol (60 ml) was dropwise added NaBH4 (2.90g, 0.077 mol) while stimng for 30 min at room temperature. After the reaction was terminated with a saturated ammonium solution, extraction with ethylacetate was carried out. The organic layer was dried over anhydrous magnesium sulfate, filtered, and concentrated. The residue was purified by chromatography to give 2-chloro-5-(trifluoromethyl)pyr’idin-3-yl-methanol (12.3g, 76%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,934279-60-4, its application will become more common.
