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. 56131-47-6, name is 1-Bromo-2-chloro-3-(trifluoromethyl)benzene, A new synthetic method of this compound is introduced below., Quality Control of 1-Bromo-2-chloro-3-(trifluoromethyl)benzene

l-Bromo-2-chloro-3-trifluoromethyl-benzene D-I-Ia (4.9 g, 18.9 mmol) is taken up in cone, sulphuric acid (20 mL), cooled to 0 0C and combined with an ice-cold mixture of cone, nitric acid (25 mL) and cone, sulphuric acid (20 mL). After 3 h stirring at RT the reaction mixture is poured onto ice water, extracted with EtOAc, the organic phase is washed with sat. NaHCO3 solution and sat. NaCl solution, dried on Na2SO4, filtered and evaporated down using the rotary evaporator and the intermediate product Z-9a obtained (HPLC-MS: tRet. = 2.14 min) is further reacted directly.

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.
