Brief introduction of 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine

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-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine, other downstream synthetic routes, hurry up and to see.

Electric Literature of 285984-25-0, 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. 285984-25-0, name is 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.

Preparation 17 l-(5-te^-Butyl-2-p-tolyl-2ff-pyrazol-3-ylVcarbamic acid 2.2.2-trichloro-ethyl ester To a solution of 5-te^-butyl-2-^-tolyl-2F-pyrazol-3-ylamine (Regan et al. J. Med. Chem. 2002, 45,2994-3008, 400 g, 1.74 mol) in THF (8L) add a saturated solution of sodium carbonate (2.4 L) and cool the mixture to 0 0C. Then add 2, 2, 2-trichloroethyl chloroformate (406.77 g, 1.92 mol) dropwise and stir mixture at 0 0C for 2 hours. Extract the reaction mixture with ethyl acetate (3 x 6.5L), dry over anhydrous magnesium sulfate and evaporate the solvent. Dissolve the solid in a minimum amount of ethyl acetate and add an excess of hexanes to precipitate the solid. Collect the solid by filtration and dry to obtain the title compound as an off white solid (586 g, 83% yield). (ES+): m/z 406.1 (M+H).
