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. 95470-42-1, name is Ethyl 2-bromo-4-methyl-1H-imidazole-5-carboxylate, A new synthetic method of this compound is introduced below., SDS of cas: 95470-42-1
Ethyl 2-bromo-1-(cyclopropylmethyl)-4-methyl-1H-imidazole-5-carboxylate (EV-AT8650-001)? Step 2 To ethyl 2-bromo-4-methyl-1H-imidazole-5-carboxylate (EV-AT8648-001, 550 mg, 2.36 mmol) in DMF (10 ml), was added potassium carbonate (652 mg, 4.72 mmol) followed by (bromomethyl)cyclopropane (0.25 ml, 2.60 mmol) and the reaction mixture stirred at room temperature for 16h. Saturated aqueous ammonium chloride (150 ml) was added to the reaction mixture and the aqueous layer was extracted with ethyl acetate (2×150 ml). The combined organics were then dried over sodium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography (0-100percent ethyl acetate/heptane) to afford 543 mg (80percent) of ethyl 2-bromo-1-(cyclopropylmethyl)-4-methyl-1H-imidazole-5-carboxylate (EV- AT8650-001) as a colourless oil. LCMS (method D): retention time 1.23 min, M/z = 287/289 (M + 1).
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.
