Discovery of 626-40-4

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3,5-Dibromoaniline, and friends who are interested can also refer to it.

Synthetic Route of 626-40-4, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 626-40-4 name is 3,5-Dibromoaniline, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

Compound II (2.25 g, 10 mmol), compound III (2.51 g, 10 mmol) and diisopropylethylamine (DIPEA,3.88 g, 30 mmol) was dissolved in 50 mL of dry xylene and then warmed at reflux under nitrogen until the reaction was completeOften 5 hours). The reaction mixture was carefully poured into 200 mL of ice water, stirred and extracted with 50 mL × 3 CH 2 Cl 2. The combined extracts were driedWashed sequentially with 1% dilute hydrochloric acid (200 mL) and brine (100 mL) and dried over anhydrous sodium sulfate. Remove the desiccant by suction filtrationEvaporation on a rotary evaporator gave Compound IV as a white solid
