Adding a certain compound to certain chemical reactions, such as: 19056-40-7, name is 4-Bromo-3-methoxyaniline, 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 19056-40-7, Application In Synthesis of 4-Bromo-3-methoxyaniline
The mixture of 4-bromo-3-methoxyaniline (2-111, 1 g, 4.97 mmol), pyridine (785mg, 9.94 mmol) and cyclopropanesulfonyl chloride (696 mg, 4.97 mmol) in DCM (20 mL)was stirred at 40 °C rt for 16 h. Upon reaction completion, the resulting mixture was filtered,concentrated to remove the solvent. The resulting residue was purified by silica gelchromatography (Pet Ether/ethyl acetate = 1/1) to obtain title compound 2-112 (yellow solid,1.2 g, 79percent yield). LCMS: 306 [M + Hj .
