The important role of 34091-51-5

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5-Iodo-1-methyl-1H-pyrazole, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 34091-51-5, name is 5-Iodo-1-methyl-1H-pyrazole, 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 34091-51-5, SDS of cas: 34091-51-5

Example 41 N-[(2-Chloro-3,4-difluorophenyl)methyl]-3-methyl-1 -(1 -methyl-1 H- pyrazol-5-yl)-2-oxo-4-imidazolidinecarboxamide (E41) (in a form obtainable or prepared from (4S)-2-oxo-3-{[(phenylmethyl)oxy]carbonyl}-4-imidazolidinecarboxylic acid); To a stirred mixture of N-[(2-chloro-3,4-difluorophenyl)methyl]-3-methyl-2-oxo-4- imidazolidinecarboxamide (60.7 mg, 0.2 mmol) (prepared as described in Example 28), 5-iodo-1-methyl-1 H-pyrazole (41.6 mg, 0.2 mmol) in 1 ,4-dioxane (4 ml) was added potassium phosphate (212 mg, 1 mmol), copper (I) iodide (38.1 mg, 0.2 mmol) and trans-N,N-dimethylcyclohexane-1 ,2-diamine (0.032 ml, 0.2 mmol) and the mixture was heated at reflux under argon for 1 h. The mixture was cooled to room temperature and partitioned between saturated sodium hydrogen carbonate solution and dichloromethane. The organic extracts were separated, washed with water and brine, dried and evaporated. The residue was purified by mass-directed automated HPLC to give N-[(2-chloro-3,4-difluorophenyl)methyl]-3-methyl-1-(1-methyl-1 H- pyrazol-5-yl)-2-oxo-4-imidazolidinecarboxamide (18 mg, 23%). LC/MS [M+H]+ = 384, retention time = 2.22 minutes.
