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. 626-40-4, name is 3,5-Dibromoaniline, A new synthetic method of this compound is introduced below., name: 3,5-Dibromoaniline
EXAMPLE 15 4,5-Dibromopyrrole-2-carboxylic acid (10 g., 0.037 mole) was converted to the corresponding acid chloride by reaction with 15 ml. of thionyl chloride, and the acid chloride dissolved in 25 ml. of benzene was reacted with 9.4 g. (0.037 mole) of 3,5-dibromoaniline in 50 ml. of pyridine using the procedure described above in Example 3. The product was recrystallized from an ethyl acetate/ethanol mixture to give 14.5 g. of 3′,4,5,5′-tetrabromopyrrole-2-carboxanilide, m.p. 244-245 C.
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.
