Adding a certain compound to certain chemical reactions, such as: 288-13-1, name is 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 288-13-1, Product Details of 288-13-1
To a solution of 1H-pyrazole (5.00 g) in toluene (67.0 mL) were added dimethylsulfamoyl chloride (7.89 mL) and triethylamine (13.3 mL) at room temperature, and the reaction mixture was stirred at room temperature for 18 hr. The resulting solid was removed by filtration, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (6.24 g). 1H NMR (400 MHz, CDCl3) delta 2.91 (6H, s), 6.38 (1H, dd, J = 2.6, 1.8 Hz), 7.72 (1H, d, J = 1.2 Hz), 7.96 (1H, d, J = 2.4 Hz)
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, 1H-Pyrazole, other downstream synthetic routes, hurry up and to see.
