Synthetic Route 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.
Step 3 (R)-N-(1-(3-isopropyl-1H-pyrazole-5-carbonyl) pyrrolidin-3-yl)cyclopro pane carboxamide To a solution of 3-isopropyl-1H-pyrazole-5-carboxylic acid (220 mg, 1.43 mmol) in DMF (5 mL) was added HATU (690 mg, 1.82 mmol) and DIPEA (0.7 mL, 0.39 mmol) at room temperature. The reaction mixture was stirred for 30 mm and then (R)-N-(pyrrolidin-3-yl) cyclopropanecarboxamidehydrochloride (200 mg, 1.30 mrnol) was added and the mixture was stirred for another 2 his. Thenthe mixture was filtered and purified by preparative HPLC to give desired product (136.8 mg, 36%yield). ?HNMR (400 MHz, CD3OD) 6 6.48 (s, 111), 4.41 – 4.38 (m, IH), 4.03 – 3.75 (m, 4H), 3.05 -3.02 (m, IH), 2.20-2.15 (m, 11-I), 1.97 1.96 (m, 1H), 1.59- 1.57 (m, IH), 0.86-0.82 (m, 2H),0.75 – 0.73 (m, 2H). LCMS (ESI) mlz: 291.1 [M+Hj, RT = 0.687 mm (LCMS Method E).
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.
