Electric Literature 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 (515 mg), 2,5-dimethoxyphenylboronic acid (642 mg) and Pd(dppf)CI2-CH2CI2 ( 05 mg) in a mixture of THF (15 mL) and sodium carbonate solution (2 M, 3 mL) was heated in a microwave (Biotage) to 100 C for 1.5 h. The mixture was chilled, the layers separated and the aqueous layer was extracted with EtOAc. The combined organic layers were dried and the volatiles were removed under reduced pressure. The residue was purified by chromatography (Interchim cartridge 50SiHP / 25 g, Cy / EtOAc) to yield the desired compound (77% yield). LC-MS (Method 2): m/z [M+H]+ = 277.1 (MW calc. = 276.29); R, = 0.62 min.
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, Methyl 5-bromo-1-methyl-1H-pyrazole-3-carboxylate, other downstream synthetic routes, hurry up and to see.
