Continuously updated synthesis method about 54962-75-3

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Bromo-5-(trifluoromethyl)aniline, its application will become more common.

Application of 54962-75-3,Some common heterocyclic compound, 54962-75-3, name is 3-Bromo-5-(trifluoromethyl)aniline, molecular formula is C7H5BrF3N, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: A mixture of CuI (190mg, 1mmol), 4-methyl-1H-imidazole (1.64g, 20mmol), Cs2CO3(3.25g, 10mmol), 3-bromo-5-(trifluoromethyl)aniline (2.40g, 10 mmol), 1-(5,6,7,8-tetrahydroquinolin-8-yl)ethanone (350mg, 2mmol) and DMF (30mL) was added to a bottom, the bottom was evacuated and backfilled with argon (this procedure was repeated three times), then the mixture was heated to 130 C for 24 h under argon. After cooling to room temperature, the solvent was removed under vacuum and the residue was purified by column chromatography on silica gel to afford the crude product. The crude product was recrystallized as a white solid (1.7 g, 71%)

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-Bromo-5-(trifluoromethyl)aniline, its application will become more common.
