Application of 10394-38-4, 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. 10394-38-4, name is 1-Methylbenzoimidazol-5-amine belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
12.5 N-(1-methyl-1H-benzimidazol-5-yl)-5-fluoro-1-[(3-fluorophenyl)methyl]-1H-pyrrolo[2,3-b]pyridine-2-carboxamide; 0.18 g (1.23 mmol) of 5-amino-1-methylbenzimidazole and 10 ml of dry toluene are placed, while flushing with nitrogen, in a 100 ml three-necked flask cooled to 0 C. and equipped with a magnetic stirrer. To this solution is then added slowly 0.95 ml (1.90 mmol) of a 2M solution of trimethylaluminum in toluene. The reaction mixture obtained is maintained under a nitrogen atmosphere and stirred, while allowing the temperature to rise gradually to 70 C. A solution of 0.3 g (0.95 mmol) of product obtained in step 12.4 in 10 ml of dry toluene is then added dropwise over 5 minutes using an addition funnel. The reaction mixture is then refluxed for 5 hours and stirred at room temperature overnight. 20 ml of cold water are then added to the solution cooled to 0 C., followed by addition of 10 ml of 1N hydrochloric acid. After stirring for 1 hour, the precipitate is recovered by filtration, rinsed with water and dried under reduced pressure. 0.22 g (0.53 mmol) of the expected product is obtained in the form of a white solid.Melting point: 266-268 C.1H NMR (DMSO D6), delta (ppm): 9.5 (s, 1H); 8.5 (s, 1H); 7.9 (s, 2H); 7.5 (m, 3H); 7.3-6.8 (m, 5H); 5.9 (s, 2H); 3.95 (s, 3H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 1-Methylbenzoimidazol-5-amine, other downstream synthetic routes, hurry up and to see.
