Adding a certain compound to certain chemical reactions, such as: 82560-12-1, name is 3-Amino-5-tert-butylpyrazole, 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 82560-12-1, COA of Formula: C7H13N3
3-Tert-butyl-1 H-pyrazol-5-amine (J-lll) (1 equivalents, 40 g) was dissolved in diluted HCI (120 mL of HCI in 120 mL of water) and mixed dropwise with NaN02 (1 .03 equivalents, 25 g in 100 mL) at 0 – 5 C over a period of 30 min. After stirring for 30 minutes, the reaction mixture was neutralised with Na2C03. A diazonium salt obtained by reaction of KCN (2.4 equivalents, 48 g), water (120 mL) and CuCN (1 .12 equivalents, 31 g) was added dropwise to the reaction mixture within 30 min and the mixture was stirred for a further 30 min at 75 C. After complete reaction, the reaction mixture was extracted with ethyl acetate (3 x 500 mL), the combined organic phases were dried over sodium sulphate and the solvent was removed under vacuum. The purification (silica gel: 100-200 mesh, eluent: 20 % ethyl acetate/n-hexane) of the residue by column chromatography produced a white solid (J-IV) (6.5 g, 15 %).
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-Amino-5-tert-butylpyrazole, other downstream synthetic routes, hurry up and to see.
