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, SDS of cas: 82560-12-1
To a solution of methyl-4-iodo-2-methoxybenzoate (10.0 g, 34.2 mmol) in toluene (90 mL) was added 3-tert-butyl-1H-pyrazol-5-amine (5.24 g, 37.7 mmol) followed by (1R,2R)-N1,N2-dimethylcyclohexane-1,2-diamine (870 mg, 1.08 mL, 6.85 mmol) and potassium carbonate (14.9 g, 108 mmol). The mixture was purged with N2, copper(I) iodide (326 mg, 1.71 mmol) was added and the reaction mixture was heated at reflux under N2 for 18 hr. The mixture was cooled to RT and was partitioned between EtOAc (100 mL) and water (3×150 mL). The organic layer was separated and washed with aq. citric acid solution (1% w/v, 150 mL) followed by water (150 mL), and was then dried and evaporated in vacuo. The residue was purified by flash column chromatography (SiO2, 330 g, EtOAc in isohexane, 0-100%, gradient elution) to afford methyl 4-(5-amino-3-tert-butyl-1H-pyrazol-1-yl)-2-methoxybenzoate as a buff coloured solid (3.62 g, 35%); Rt 1.93 min (Method 2); m/z 304 (M+H)+ (ES+).
