Adding a certain compound to certain chemical reactions, such as: 58534-95-5, name is 3-Bromo-2-fluoroaniline, belongs to bromides-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 58534-95-5, category: bromides-buliding-blocks
To a solution of 3-bromo-2-fluoro-phenylamine (1.10 g, 5.67 mmol) in DCM (50 mL) was added pyridine (0.68 mL, 8.51 mmol), 3-chloro-4-methoxy-benzenesulfonyl chloride (1.37 g, 5.70 mmol) and stirred at room temperature overnight. The reaction mixture was diluted with DCM, washed with saturated aqueous NaHC03, saturated aqueous NH4CI, brine and dried over Na2S04. The organic solvent was removed under reduce pressure and the crude triturated with Et2O to give the title compound (1.63 g) as a white solid. HPLC (254 nm): Rt: 5.74 min. HRMS (ESI) calcd for C13H10BrCIFNO3S [M+Na]+ 415.9129, found 415.9135. 1H NMR (600 MHz, DMSO-d6) delta ppm: 3.93 (s, 3 H) 7.10 (td, J=8.10, 1.19 Hz, 1 H) 7.22 – 7.25 (m, 1 H) 7.31 (d, J=8.79 Hz, 1 H) 7.47 – 7.52 (m, 1 H) 7.66 (dd, J=8.70, 2.29 Hz, 1 H) 7.74 (d, J=2.38 Hz, 1 H) 10.37 (s, 1 H).
