Adding a certain compound to certain chemical reactions, such as: 285984-25-0, name is 3-(tert-Butyl)-1-(p-tolyl)-1H-pyrazol-5-amine, 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 285984-25-0, Recommanded Product: 285984-25-0
General procedure: A solution of compounds 10a-d or compounds 17a-d (1.0 mmol) in dichloromethane (10 mL) was slowly added to a stirred solution of triphosgene (109 mg, 0.36 mmol) in dichloromethane (50 mL) over a period of 30 min using a syringe. After stirring for a further 30 min, a solution of compound 25a-r (0.6 mmol) and triethylamine (0.4 mL, 2.77 mmol) in dichloromethane (10 mL) was added in one portion. The reaction mixture was stirred for 2 h at room temperature. After completion of the reaction, the reaction was poured into water (50 mL) and extracted three times with dichloromethane. The organic layer was washed with water (5 mL), sat. NaCl solution (5 mL), anddried over Na2SO4. After evaporation of solvent under vacuum, the residue was purified by silica gel chromatography to give the desired chromanylurea or 2H-chromenyl urea compounds.
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.
