Synthetic Route of 16078-71-0, 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. 16078-71-0, name is Ethyl 5-amino-1-phenyl-1H-pyrazole-4-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
Preparation of compound 1-2 [80] The compound 1-1 (30 g, 0.12 mol) was dissolved in hydrazine hydrate (70 mL) and the mixture was stirred for 2hours at 100C. Upon completion of the reaction, the temperature was slowly raised to room temperature and then a solid was produced. Washing the solid with diethyl ether and filtering under reduced pressure gave a compound 1-2(26g,92%).
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, Ethyl 5-amino-1-phenyl-1H-pyrazole-4-carboxylate, other downstream synthetic routes, hurry up and to see.
