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. 614-97-1, name is 5-Methyl-1H-benzo[d]imidazole, A new synthetic method of this compound is introduced below., SDS of cas: 614-97-1
To a solution of compound DD2 (24.5 mmol) in CH3CN (65 mL) was added di-tertbutyl dicarbonate (5.89 g, 27.0 mmol), triethylamine (3.76 mL, 27.0 mmol) and 4-dimethylamino pyridine (300 mg, 2.45 mmol) and the resulting reaction was heated to 80 C. and allowed to stir at this temperature for 1.5 hours. The reaction mixture was cooled to room temperature, concentrated in vacuo, and the residue obtained was purified using flash column chromatography (silica gel, EtOAc/Hexanes 5-20%) to provide a mixture of isomeric compounds DD3 and DD4 (5.38 g, 94.3% yield over steps A and B).
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.
