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. 112734-22-2, name is (4-Bromo-2-fluorophenyl)methanamine, A new synthetic method of this compound is introduced below., HPLC of Formula: C7H7BrFN
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 1N HCl 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%).
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.
