Adding a certain compound to certain chemical reactions, such as: 6911-87-1, name is 4-Bromo-N-methylaniline, 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 6911-87-1, Quality Control of 4-Bromo-N-methylaniline
General procedure: To a solution of substituted N-methylaniline (1mmol) in CH2Cl2 (5mL) was added aqueous NaOH 25M (1mL) followed by tetrabutylammonium hydrogen sulfate (0.15mmol). After 5min of vigorous stirring, the substituted benzenesulfonyl chloride (1mmol) was added to the reaction mixture. The solution was stirred either for 3h or overnight at room temperature. Water was added to quench the reaction. Aqueous layer was extracted with CH2Cl2 (3×CH2Cl2). The organic layer was washed once with brine and once with water, dried over MgSO4, filtered and concentrated under reduced pressure. The residue was purified by column chromatography using a mixture of n-hexane and ethyl acetate as solvent to afford the desired compound.
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-N-methylaniline, other downstream synthetic routes, hurry up and to see.
