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. 175137-46-9, name is 5-Cyclopropyl-1H-pyrazol-3-amine belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.

101B. 2-Chloro-4-(5-cyclopropyl-1H-pyrazol-3-ylamino)pyrrolo[1,2-f][1,2,4]triazine-7-carbaldehyde A mixture of 101A (371 mg, 1.72 mmole), 5-cyclopropyl-1H-pyrazol-3-amine (139 mg, 1 equiv), and diisopropylethylamine (0.51 mL, 1.7 equiv) in isopropyl alcohol (1.7 mL) was stirred at RT overnight. The reaction was diluted with a mixture of dichloromethane_methanol=9:1, washed with water and dried (Na2SO4). Removal of the solvents followed by radial silica gel chromatography (step gradient elution with mixtures of dichloromethane containing 0 to 7.5% methanol) afforded the product as a solid (279 mg, 54% yield): MS: 303 (M+H)+; HPLC Ret Time: 2.61 min (Phenomenex-Luna S10 3.0*50 mm column, 3 min gradient, 4 mL\/min).<\/p>\n

The synthetic route of 175137-46-9 has been constantly updated, and we look forward to future research findings.<\/p>\n
