672-57-1, Adding a certain compound to certain chemical reactions, such as: 672-57-1, name is 1-Chloro-2-iodo-4-(trifluoromethyl)benzene, belongs to iodides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 672-57-1.
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.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Chloro-2-iodo-4-(trifluoromethyl)benzene, other downstream synthetic routes, hurry up and to see.
