Synthetic Route of 1222174-92-6, 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. 1222174-92-6, name is Methyl 5-bromo-1-methyl-1H-pyrazole-3-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
A solution of intermediate 2a (506 mg) in dioxane (10 mL) was treated with LiOH solution (2 M, 1 mL) and the mixture was stirred at 70 C. for 1 h. HCl (1 M) was added and the mixture was extracted with EtOAc. The combined organic layers were dried and the volatiles were removed under reduced pressure to yield the desired compound (84% yield). [0358] LC-MS (Method 2): m/z [M+H]+=205.0 (MW calc.=205.01); Rt=0.31 min.
The synthetic route of Methyl 5-bromo-1-methyl-1H-pyrazole-3-carboxylate has been constantly updated, and we look forward to future research findings.
