Reference of 33468-69-8, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 33468-69-8, name is 4-(Trifluoromethyl)-1H-imidazole, This compound has unique chemical properties. The synthetic route is as follows.
Intermediate (3): 1-(2-methyl-4-nitrophenyl)-4-(trifluoromethyl)-1H-imidazole A mixture of 4-(trifluoromethyl)-1H-imidazole (198 mg, 1.46 mmol), 1-fluoro-2-methyl-4-nitrobenzene (216 mg, 1.53 mmol) and potassium carbonate (402 mg, 2.91 mmol) in acetonitrile (1.5 mL) was heated to 85 C. for 24 hours. The mixture was diluted with water and saturated ammonium chloride and was extracted with ethyl acetate twice. The combined organic layers were dried over sodium sulfate, filtered and concentrated. Purification by column chromatography (0-50% ethyl acetate in heptane), gave 1-(2-methyl-4-nitrophenyl)-4-(trifluoromethyl)-1H-imidazole. 1H NMR (500 MHz, CDCl3, delta): 8.30 (d, J=2.44 Hz, 1H), 8.21-8.25 (m, 1H), 7.70 (s, 1H), 7.45-7.49 (m, 2H), 2.38 (s, 3H).
The chemical industry reduces the impact on the environment during synthesis 4-(Trifluoromethyl)-1H-imidazole. I believe this compound will play a more active role in future production and life.
