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. 6358-77-6, name is 5-Bromo-2-methoxyaniline, A new synthetic method of this compound is introduced below., HPLC of Formula: C7H8BrNO
5-(Dimethylphosphoryl)-2-methoxyaniline (0456) To a solution of 5-bromo-2-methoxyaniline (0.404 g, 2.00 mmol) in 8 mL DMF was added dimethylphosphine oxide (0.171 g, 2.20 mmol), palladium acetate (22.4 mg, 0.0100 mmol), XANTPHOS (69.4 mg, 0.120 mmol), and potassium phosphate (0.467 g, 2.20 mmol). The mixture was purged with nitrogen, and subjected to microwaves at 150 C. for 20 minutes. The reaction mixture was concentrated and purified by silica gel chromatography (0-20% 7N ammonia in methanol:dichloromethane) to afford the desired product (0.365 g, 85% yield).
The synthetic route of 6358-77-6 has been constantly updated, and we look forward to future research findings.
