Adding a certain compound to certain chemical reactions, such as: 261723-28-8, name is (3-Bromo-2-fluorophenyl)methanamine, belongs to bromides-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 261723-28-8, category: bromides-buliding-blocks
Example 58 1,1-Dimethylethyl[(3-bromo-2-fluorophenyl)methyl]carbamate To a suspension of [(3-bromo-2-fluorophenyl)methyl]amine (5.0 g, 20.3 mmol) and Na2CO3 (5.5 g, 51.9 mmol) in CH2Cl2 (100 mL), was added dropwise a solution of Boc2O (4.5 g, 20.6 mmol) in CH2Cl2 (10 ml). Then the reaction mixture was stirred overnight at room temperature. After filtration, the solid was washed with CH2Cl2 (50 mL*2), and then the filtrate was washed with water (70 mL*2), brine (70 mL*2) and dried over Na2SO4. After removing the solvent, 5.6 g of 1,1-dimethylethyl[(3-bromo-2-fluorophenyl)methyl]carbamate was obtained (yield: 94%).
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, (3-Bromo-2-fluorophenyl)methanamine, other downstream synthetic routes, hurry up and to see.
