Adding a certain compound to certain chemical reactions, such as: 38762-41-3, name is 4-Bromo-2-chloroaniline, belongs to chlorides-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 38762-41-3, 38762-41-3
Example 209 Ethanesulfonic acid [5-(8-chloro-l-methyl-2-oxo-l,2,3,4-tetrahydro-quinolin-6-yl)- pyridin-3-ylmethyl] -amide[A] N-(4-Bromo-2-chloro-phenyl)-3-chloro-propionamideTo a solution of 4-bromo-2-chloro-phenylamine (32 g, 0.15 mol) and pyridine (13.45 g, 0.17 mol) in DCM (200 mL) was added 3-chloropropionyl chloride (21.65 g, 0.17 mol) dropwise at 15 C. After stirring at room temperature for 1 hour, the mixture was washed with water and then hydrochloric acid (2 N, aqueous). The organic layer was dried over anhydrous Na2S04, filtered, and concentrated in vacuo to afford title compound (10.9 g, yield: 90%) as a white solid.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Bromo-2-chloroaniline, other downstream synthetic routes, hurry up and to see.
