Related Products of 454-78-4, 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. 454-78-4, name is 2-Bromo-1-chloro-4-(trifluoromethyl)benzene, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: To an oven-dry ground test tube equipped with a stir bar were added 1 mmol 2-bromoiodobenzene, 1mmolL-alaninamide, 3 mmol potassium carbonate and 5 mL DMF. The test tube was sealed with a rubber stopperand was evacuated and refilled with argon for three times. Then the test tube was stirred in an oil bathpreheated at 90? C for 48 hours. After the test tube was cooled to room temperature, the reaction wasquenched with water, and the reaction mixture was extracted with 20 mL ethyl acetate for three times. Thecombined organic layer was washed with 10 mL water and then saturated sodium chloride aqueous solution,and dried over anhydrous sodium sulfate. After filtration, the filtrate was condensed on a rotary evaporator invacuum. The resulting crude product was chromatographed on silica gel (300-400 mesh) with a 1:2 volumeratio mixed solution of ethyl acetate and petroleum ether as eluent to give a white solid L-N-phenylalaninamide.
The chemical industry reduces the impact on the environment during synthesis 2-Bromo-1-chloro-4-(trifluoromethyl)benzene. I believe this compound will play a more active role in future production and life.
