Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 418762-26-2, name is 4-Bromo-2-fluoro-5-methylaniline, A new synthetic method of this compound is introduced below., Recommanded Product: 418762-26-2
To a stirred solution of 4-(2-(benzyloxy)ethoxy)-l-methyl-lH-pyrazole-5-carbonyl chloride (0.9 g, 3.05 mmol, 1 equiv) and 4-bromo-2-fluoro-5-methylaniline (0.6 g, 3.05 mmol, 1 equiv) in DCM was added Et3N (0.5 g, 4.58 mmol, 1.5 equiv) at 0 C under nitrogen atmosphere. The resulting solution was stirred for 30 min. The reaction was quenched with water at room temperature. The aqueous layer was extracted with CH2CI2 and the organic layer was concentrated under reduced pressure to give the title compound (1 g, 70.84%) as a white solid. LC-MS: (ES, m/z): [M+H]+ 462.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
