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. 2301-25-9, name is 1-(4-Nitrophenyl)-1H-imidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. Application In Synthesis of 1-(4-Nitrophenyl)-1H-imidazole
Part A. Preparation of 1-(4-aminophenyl)imidazole. 1-(4-Nitrophenyl)imidazole (5.0 g) and 200 mL of methanol were combined to form a solution at ambient temperature. The addition of a catalytic amount of 10% palladium on carbon turned the solution into a suspension. Placement of the reaction mixture under a hydrogen atmosphere initiated the reduction. The reaction proceeded overnight (15 h) at ambient temperature. Filtration through a celite pad separated out the catalyst. Concentration of the filtrate under reduced pressure gave the title product as a pale yellow solid (3.99 g). 1 H-NMR(DMSO d6) delta: 7.95 (s, 1H), 7.45 (s, 1H), 7.18 (d, 2H), 6.99 (s, 1H), 6.60 (d, 2H), 5.25 (s, 2H) ppm. LRMS(GC/MS) m/z 160 (M+H, 100).
The synthetic route of 2301-25-9 has been constantly updated, and we look forward to future research findings.
