Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 82560-12-1, name is 3-Amino-5-tert-butylpyrazole, A new synthetic method of this compound is introduced below., Safety of 3-Amino-5-tert-butylpyrazole<\/a><\/p>\n

5-tert-Butyl-2H-pyrazol-3-ylamine (1.11 g, 8.00 mmol), potassium carbonate (2.32 g, 16.8 mmol), copper (I) iodide (0.076 g, 0.40 mmol), and 3-bromo-5- methylphenol (1.80 g, 9.60 mmol) were weighed into a large microwave vial. This was then purged with argon then trans-N,N-dimethylcyclohexane-l,2-diamine (0.25 mL, 1.60 mmol) added. To this mixture was then added degassed toluene (8 mL). The mixture was then purged with argon again, the vial sealed, and heated for 1 h at 140 C in the microwave, then a further 4 h at 135 C. The mixture was cooled, diluted with ethyl acetate and passed through a pad of celite\/silica, washing with more ethyl acetate. The dark solution was concentrated in vacuo. The residue was purified by FCC, using 0-40% DCM in EtOAc, to give the title compound (966 mg, 49%). NMR (300 MHz, CDC13): 1.32 (9H, s), 2.24 (3H, s), 3.82 (2H, br s), 5.49 (1H, s), 6.45-6.52 (1H, m), 6.65-6.71 (1H, m), 6.85-6.91 (lH, m).<\/p>\n

The synthetic route of 82560-12-1 has been constantly updated, and we look forward to future research findings.<\/p>\n
