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. 118430-73-2, name is 3-(tert-Butyl)-1-methyl-1H-pyrazol-5-amine belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C8H15N3
[140] To a 100 mL oven dried flask, was added 5-AMINO-3-TETT-BUTYL-1-METHYLPYRAZOLE (2.00 G, 13.1 MMOL), methyl 2-bromo-5-methoxybenzoate (2.67 g, 10.9 MMOL), cesium carbonate (4.96 g, 15.2 mmol), Pd2 (dba) 3 (337 mg, 0.33 MMOL), BINAP (338 mg, 0.54 MMOL), and toluene (35 mL). The reaction mixture was degassed, placed under an N2 atmosphere, and then stirred at 110C for 16 h. The reaction mixture was cooled to rt, and ethyl acetate (30 mL) was added. The mixture was filtered, the filter cake washed with EtOAc (10 mL), and the filtrate concentrated under reduced pressure. The residue was purified by silica gel flash chromatography (eluent : 10 to 30% EtOAc in hexane) to give the title compound as a light yellow oil (1.34 g, 38%).’H NMR (400 MHz, CDCIG) 8 1. 28 (s, 9H), 3.63 (s, 3H), 3.78 (s, 3H), 3.94 (s, 3H), 5.97 (s, 1H), 6.82 (d, 1H), 7.10 (dd, 1 H), 7.47 (d, 1 H).
The synthetic route of 118430-73-2 has been constantly updated, and we look forward to future research findings.
