Adding a certain compound to certain chemical reactions, such as: 175137-46-9, name is 5-Cyclopropyl-1H-pyrazol-3-amine, 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 175137-46-9, 175137-46-9
Example 2; N-(3-cyclopropyl-1H-pyrazol-5-yl)-2-{[3-(methyloxy)phenyl]sulfanyl}pyrrolo[2,1-f][1,2,4]triazin-4-amine; 2A. 2-Chloro-N-(5-cyclopropyl-1H-pyrazol-3-yl)pyrrolo[1,2-f][1,2,4]triazin-4-amine; A mixture of 1B (977 mg, 5.2 mmol), 5-cyclopropyl-1H-pyrazol-3-amine (640 mg, 1 equiv), and diisopropylethylamine (1.54 mL, 1.7 equiv) in 5 mL IPA was stirred at RT overnight. The precipitate was collected by filtration to give 1.18 g 2A (83% yield). 1H NMR (CDCl3): 0.67 (m, 2H), 0.86 (m, 2H), 1.77 (m, 1H), 6.6 (br. s, 1H), 6.54 (br.s, 1H), 6.79 (br. s, 1H), 7.42 (br.s, 1H); MS: 275 (M+H)+; and RP HPLC ret. t.: 1.56 min (Phenomenex-Luna S10: 3.0¡Á50 mm column, 2 min gradient, 4 mL/min).
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-Cyclopropyl-1H-pyrazol-3-amine, other downstream synthetic routes, hurry up and to see.
