Continuously updated synthesis method about 133228-21-4

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, N,N-Dimethyl-1H-pyrazole-1-sulfonamide, other downstream synthetic routes, hurry up and to see.

Adding a certain compound to certain chemical reactions, such as: 133228-21-4, name is N,N-Dimethyl-1H-pyrazole-1-sulfonamide, 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 133228-21-4, category: pyrazoles-derivatives

12. 3-Ethyl-pyrazole-l-sulphonic acid dimethylamideTo a solution of pyrazole-1-sulphonic acid dimethylamide (13. Ig, 74.9 mmol) in anhydrous tetrahydrofuran (100 ml) at -78 0C under a nitrogen atmosphere was added dropwise a solution of n-butyl lithium in hexanes (1.6M, 51 ml, 82.3 mmol). The reaction was stirred thus for 30 minutes then iodoethane (6.6 ml, 82.4 mmol) was added dropwise. The reaction mixture was allowed to warm to room temperature then stirred thus over the weekend. EPO Water was then added and the solution was extracted with ethyl acetate. The separated organic liquors were washed with brine, dried (MgSO4) and concentrated to furnish the title compound as a yellow/ brown oil (12.6g, 85%).

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, N,N-Dimethyl-1H-pyrazole-1-sulfonamide, other downstream synthetic routes, hurry up and to see.
