Reference of 92933-47-6, 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. 92933-47-6, name is 5-Isopropyl-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 a solution of HATU (174.17 mg, 0.459 mmol) and 3-isopropylpyrazole-5-carboxylic acid (59.85 mg, 0.388 mmol) in DMF (2 mL) was then added diisopropylethylamine (92 muL, 0.529 mmol). The reaction solution was stirred at room temperature for 2 h. The N-(3-cyano-4,5,6,7-tetrahydrothieno[2,3-c]pyridin-2-yl)benzamide (100 mg, 0.353 mmol) was added in one portion. The solution was then stirred at room temperature overnight. The reaction was diluted with methylene chloride and washed. The aqueous layer was extracted with methylene chloride twice, the combined organic phases were dried over anhydrous MgSO4. After evaporation of the solvent and recrystallization from ethyl acetate, filtered and dried to give desired compound (50 mg, 34%).
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-Isopropyl-1H-pyrazole-3-carboxylic acid, other downstream synthetic routes, hurry up and to see.
