Introduction of a new synthetic route about 3-Amino-5-tert-butylpyrazole

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.

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, 82560-12-1

To a mixture of Intermediate 7a (1.50 g, 4.46 mmol), 5-tert-butyl-2H- pyrazol-3-ylamine (620 mg, 4.46 mmol), copper (I) iodide (42 mg, 0.22 mmol) and K2CO3 (1.29 g, 9.37 mmol) was added to toluene (4.6 mL; previously degassed by using a stream of Argon). (R,R)-(-)-N,N’-Dimethyl- 1 ,2-cyclohexanediamine (141 L, 0.89 mmol) was then added and the reaction mixture was heated at 140 C for 2.5 h under microwave irradiation. The crude reaction mixture was poured into water and extracted with EtOAc (x 3). The combined organic layers were washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was purified by FCC, using a gradient of 0-100% EtOAc in cyclohexane, to give the title compound (1.14 g, 73%). LCMS (Method 4): Rt 2.34 min, m/z 348 [MH+].
