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. 37148-86-0, name is 4-(4-(Trifluoromethyl)phenyl)-1H-imidazole, A new synthetic method of this compound is introduced below., Product Details of 37148-86-0

Reference Example 2 (0.12 g)2-bromo-4-nitroaniline (0.12 g), cesium carbonate (0.28 g), copper (I) oxide (8.1 mg) and 4,7- dimethoxy-1,10 -Phenanthroline (0.027 mg) was added. The reaction solution was stirred under microwave irradiation at 180 C. for 1 hour and then cooled to room temperature. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel chromatography (elution solvent; hexane: ethyl acetate) to obtain Example 40 (30 mg).

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

These common heterocyclic compound, 37148-86-0, name is 4-(4-(Trifluoromethyl)phenyl)-1H-imidazole, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. SDS of cas: 37148-86-0

Sodium hydride (60% in oil) (32 mg) was added at 0 C. to a DMF (6.7 mL) solution of Reference Example 2 (0.17 g), and the mixture was stirred at 0 C. for 30 minutes. 2-Fluoro-4- (trifluoromethyl) benzonitrile (0.13 g) was added to the reaction solution at 0 C., and the mixture was stirred at room temperature for 3 hours. Water was added to the reaction solution, and the mixture was extracted with ethyl acetate. The obtained organic layer was washed with a saturated saline solution and dried over sodium sulfate. After evaporation of the solvent of the organic layer after drying under reduced pressure, the obtained residue was purified by silica gel chromatography (elution solvent; hexane: ethyl acetate) to obtain Reference Example 5 (0.18 g).
