Related Products of 92933-47-6, These common heterocyclic compound, 92933-47-6, name is 5-Isopropyl-1H-pyrazole-3-carboxylic acid, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

Step 3 N-(1-(3-isopropyl-1H-pyrazole-5-carbonyl)-3-metbyipyrrolidin-3-yJ)cyclopropanecarboxamideTo a solution of 3-isopropyl-1H-pyrazole-5-carboxylic acid (431 mg, 2.79 mmol) in DMF (6 mL) were added HATU (1.38 g, 3.63 mmol) and DIEA (1.85 mL, 11.18 mmol) and then stirred at room temperature for 5 minutes before the addition of N-(3 -methylpyrrolidin-3-yl)cyclopropane carboxamide hydrochloride (572 mg, 2.79 mmol) was added. The resulting mixture was stirred at room temperature for 16 hrs. The reaction mixture was filtered and the crude product was purifiedby preparative HPLC (Gemini C18, 150 x 25 mm xlO jam, 26-56% MeCN/H20) to give the desiredproduct (210 mg, 25% yield) as white solid. ?H NMR (400 MHz, DMSO-d6) 6 8.09 (s, IH), 6.41(s, IH), 4.17 – 4.14 (m, 0.SH), 3.88-3.72 (m, 2H), 3.55 -3.52 (m, 1H), 3.38 – 3.35 (m, 0.SH), 2,96-2.93 (m, IH), 2,31 -2.19 (m, 1H), 1.88- 1.72 (m, IH), 1.56- 1.53 (m, 111), 1.38 (s, 3H), 1.22(d, J 7.2 Hz, 6H), 0.63 -0.57 (m, 4H).
