Adding a certain compound to certain chemical reactions, such as: 93919-56-3, name is (4-(Trifluoromethoxy)phenyl)methanamine, belongs to ethers-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 93919-56-3, name: (4-(Trifluoromethoxy)phenyl)methanamine
General procedure: To a solution of 4 (290mg, 1.02mmol) in DMF (1.5mL), CDI (198mg, 1.23mmol) was added under N2 protection. The resulting reaction was stirred 50C. After 2h, the mixture was cooled to room temperature, and the corresponding benzylamine (1.53mmol) was added. The resulting reaction was stirred 50C under N2 protection overnight. Then the mixture was cooled to room temperature, quenched with 1M hydrochloric acid, diluted with water (50mL), and extracted with CH2Cl2 (60mL×3). The combined organic layer were washed with saturated solution of NaCl (60mL×3), dried over MgSO4, concentrated and purified by flash chromatography eluting with 5-50% ethyl acetate in petroleum ether, to provide the desired products 5a-5d.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, (4-(Trifluoromethoxy)phenyl)methanamine, and friends who are interested can also refer to it.
