In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 57090-88-7, name is 1H-Imidazole-4-carbonitrile belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. 57090-88-7
General procedure: A solution of 4-cyano-1H-imidazole (1000 mg, 10.74 mmol), 4-iodo -2-(trifluoromethyl)pyridine (3800 mg,14 mmol), (1R,2R)-N1,N2-dimethyl cyclohexane -1,2-diamine (150 mg, 1.07 mmol), CuI (200 mg, 1.07 mmol) and Cs2CO3 (7000 mg, 21.5 mmol) in 20 mL anhydrous DMF was stirred at 100 oC for 2 hours. The reaction mixture was cooled to room temperature and poured into 200 mL water. The mixture was extracted with ethyl acetate (80 mL*3). The organic layer were combined, washed by brine, dried by Na2SO4 and evaporated. The crude product was purified by silica flash column to afford compound 2 as white solid(1.5 g, 59percent yield).
The synthetic route of 57090-88-7 has been constantly updated, and we look forward to future research findings.
