Adding a certain compound to certain chemical reactions, such as: 31230-17-8, name is 5-Methyl-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 31230-17-8, Product Details of 31230-17-8
A mixture of compound C (1.0 g, 2.94 mmol)and 3-amino-5- methylpyrazole (314 mg, 3.23 mrnol) in dirnethylfo?namide (6 ml) was treated with diisopropylethylamine (0.614 ml, 3.53 mmol) and sodium iodide (530 mg, 3.53 mmol). The mixture was stirred under nitrogen at 85 for 4 hours, cooled to room temperature and diluted with ethyl acetate. The solution was washed with water (x 4), dried over magnesium sulphate and concentrated to 5 ml to afford, upon crystallization and harvesting ofcolourless crystals, the title compound D (920 mg, 78%). 1H- NMR DMSO-d5, delta 0.80-0.87 (4H, m), 1.77-1.85 (IH, m), 1.92 (IH, s), 5.24 (IH, br s), 6.47 (IH, br s), 7.55 (2H, d), 7.70-7.80 (2H, m), 10.24 (IH, s), 10.47 (IH, s), 11.92 (IH, s).
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-Methyl-1H-pyrazol-3-amine, other downstream synthetic routes, hurry up and to see.
