Adding a certain compound to certain chemical reactions, such as: 25700-12-3, name is 3-(1H-Pyrazol-1-yl)pyridine, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 25700-12-3, Formula: C8H7N3<\/a><\/p>\n

Step 2: Preparation of 3-(4-nitro-pyrazol-1-yl)-pyridine 3-Pyrazol-1-yl-pyridine (2 g, 0.032 mol) was dissolved in concentrated H2SO4 (32 mL 0.598 mmol) and cooled to -5 C. using an ice bath. To the reaction mass, a 1:1 mixture of concentrated HNO3 (30 mL, 0.673 mmol) and concentrated H2SO4 (30 ml, 15 Vol.) was added dropwise over a period of 30 min. Cooling was discontinued and the reaction mixture was stirred at room temperature overnight. After the reaction was complete, the mixture was poured over crushed ice and neutralized with saturated NaHCO3, filtered, washed with water and dried to furnish the nitro pyrazole as pale yellow solid (1.8 g, 68%): 1H NMR (400 MHz, DMSO-d6) delta 9.03 (d, J=2.8 Hz, 1H); 8.70 (dd, J=4.8, 1.6 Hz, 1H), 8.69 (s, 1H), 8.33 (s, 1H), 8.11-8.08 (m, 1H), 7.51 (dd, J=8.4, 4.8 Hz, 1H); MS (m\/z) 191 [M+1].<\/p>\n

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, 3-(1H-Pyrazol-1-yl)pyridine, other downstream synthetic routes, hurry up and to see.<\/p>\n
