872-49-1, 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. 872-49-1, name is 5-Chloro-1-methylimidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
5-Chloro-1-methyl-imidazole (4.0 g, 34.32 mmol) was dissolved in a mixture of 4.0 g of conc. nitric acid and 14 mL of water, and concentrated in vacuo to give a yellow slurry. To this mixture was added dropwise 12 g of conc. sulfuric acid and heated to 95C for 2 hours. Upon cooling, ice was added to the reaction mixture, which was then left standing 10 hours at 5C. The white precipitation was collected by filtration, washed with water, recrystallized from ethanol and dried in vacuo to give compound 60A.
The synthetic route of 5-Chloro-1-methylimidazole has been constantly updated, and we look forward to future research findings.
