Application of 51516-67-7, 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. 51516-67-7, name is 5-Amino-1-(4-chlorophenyl)-1H-pyrazole-4-carbonitrile belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: Intermediate 4 (1mmol) and the intermediate 7 (1mmol) were dissolved in ethanol to the glass flask, then HCl solution was added as a catalyst refluxed at 80C for 15-18h. After the TLC monitoring reaction was completed, the mixture was vacuum filtered and concentrated. Finally, the above crude product can be isolated and purified by column chromatography (Hexane/EtOAc=8:1) to obtain target compounds.
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, 5-Amino-1-(4-chlorophenyl)-1H-pyrazole-4-carbonitrile, other downstream synthetic routes, hurry up and to see.
