Adding a certain compound to certain chemical reactions, such as: 656-64-4, name is 3-Bromo-4-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 656-64-4, Application In Synthesis of 3-Bromo-4-fluoroaniline
General procedure: A stirred mixture of compound 5 (0.23 g, 0.001 mol), EDCI (0.23 g, 0.0012 mol), HOBt (0.16 g,0.0012 mol), aniline or aniline derivative (0.001 mol), and 20 mL DMF was reacted at room temperature overnight, and then 40 mL water was added and stirred for a quarter, before the crude was filtered and washed twice with water. The anticipated product was purified by column chromatography on silicagel using petroleum ether/ethyl acetate (2/1, volume ratio) as the eluent to afford the target compound.
