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. 7745-91-7, name is 3-Bromo-4-methylaniline, A new synthetic method of this compound is introduced below., HPLC of Formula: C7H8BrN
3-Bromo-4-methylaniline (30.4 g) was dissolved in methanol (210 mL), pyridine (43 mL) and iodine (68.4 g) were added, and the mixture was stirred at 25C for two hours. A 20% aqueous sodium thiosulfate solution (150 mL) and water (30 mL) were added to the reaction solution and the mixture was stirred at 25C for one hour. Washing with methanol/water (1/1, 100 mL) resulted in the target compound (19.1 g).
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.
