Synthetic Route 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.
A mixture of 0.28 g of 2-(3-fluoropyridin-4-yl)-5-(trifluoromethyl)benzoxazole, 0.18 g of 4-(trifluoromethyl)-lH-imidazole, 0.55 g of potassium carbonate and 2 ml of DMF was stirred while heating at 50C for 1.5 hours. Then, the reaction mixture was cooled to room temperature. Water was added to the reaction mixture, followed by extraction with ethyl acetate twice. The combined organic layers were washed with a saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.40 g of 2- { 3- [4-(trifluoromethyl)imidazole- 1 -yl]pyridin-4-yl } -5 -(trifluoromethyl)benzoxazole hereinafter, referred to as “active compound 57”).Active compound 57-NMR (CDC13) delta: 9.00 (d, J=5.2 Hz, 1H), 8.84 (s, 1H), 8.31 (d, J=5.1 Hz, 1H), 8.06-8.04 (m, 1H), 7.77-7.75 (m, 1H), 7.74-7.70 (m, 1H), 7.62 (d, J=8.6 Hz, 1H), 7.52-7.50 (m, 1H)
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.
