Reference of 112734-22-2, 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. 112734-22-2, name is (4-Bromo-2-fluorophenyl)methanamine belongs to bromides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Step 1 : (4-Bromo-2-fluorophenyl)methanamine (924 mg, 4.53 mmol) was dissolved in pyridine and ethane sulfonyl chloride (0.82 mL, 8.60 mmol) was added to the solution at 0 C. The mixture was stirred for 1 h at 0 C. Then, the mixture was quenched with 1 N HCI and extracted with ethyl acetate. Drying over magnesium sulfate and evaporation of the ethyl acetate and purified by column chromatography gave N-(4-bromo-2-fluorobenzyl)- ethanesulfonamide in pure form (1 .06 g, 79 %).
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, (4-Bromo-2-fluorophenyl)methanamine, other downstream synthetic routes, hurry up and to see.
