Electric Literature of 54006-63-2, 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. 54006-63-2, name is 5-(4-Chlorophenyl)-1H-pyrazole-3-carboxylic acid belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
General procedure: To amixture of 3-(3-chlorophenyl)-1H-pyrazole-5-carboxylic acid (14a, 133 mg, 0.60 mmol) inDMF(4 mL)was added (S)-methyl-4-(2-amino-3-phenylpropanamido)benzoate hydrochloride (12, 200 mg,0.60 mmol), N,N-diisopropyl-ethylamine (232 mg, 1.80 mmol), 1-hydroxybenzotriazole(161 mg,1.20 mmol) and N-(3-dimethylaminopropyl)-N0-ethylcarbodiimide hydrochloride (229 mg, 1.20 mmol)and the reaction mixture was stirred at room temperature overnight.Then TLC analysis indicatedreaction was complete, and H2O (40 mL) was added.The mixture was stirred for 10 min and filtered toget crude product 13a as a yellow solid, which was used for next step without further purification.
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-(4-Chlorophenyl)-1H-pyrazole-3-carboxylic acid, other downstream synthetic routes, hurry up and to see.
