Electric Literature of 7745-91-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7745-91-7, name is 3-Bromo-4-methylaniline belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
57.62 g (0.3 mol, 1 eq) of 3-bromo-4-methylaniline are added to a solution of 75.8 g (0.344 mol, 1.15 eq) of di-tert-butyl dicarbonate in 580 mL of 2N sodium hydroxide solution. The reaction medium is refluxed for one hour and stirred at room temperature for 4 hours. The reaction medium is filtered and the solid is washed with water until the filtrate is neutral, and then dried. 90.33 g of tert-butyl (3-bromo-4-methylphenyl)carbamate are obtained in solid form.Crude yield > 100%
The synthetic route of 3-Bromo-4-methylaniline has been constantly updated, and we look forward to future research findings.
