(4-Bromo-1-methyl-1H-pyrazol-3-yl)methanol Chemical Properties,Usage,Production
Application
(4-Bromo-1-methyl-3-pyrazolyl)methanol has a simple structure and many active groups, making it a good intermediate. Its derivatives are known to be used in pharmaceuticals, aerospace, functional materials, petroleum processing and other fields.
Synthesis
The reaction system was protected with nitrogen, 171g of methyl 4-bromo-1-methyl-3-pyrazole carboxylate was put into a flask, 600g of toluene (chlorobenzene, benzene, p-toluene, etc. can also be used) was added, stirred for clarification, and the flask was cooled with an ethanol-dry ice bath. When the internal temperature -10 C, began to drop 455 g of red aluminum (70% of the toluene solution), drop over the process of exothermic, at first there is a trace of moisture in the reaction system, resulting in the drop of red aluminum outgassing, control the speed of the drop of red aluminum, so that the temperature does not exceed 0 C. Red aluminum drop after the completion of stirring at a temperature of -10-0 for 30min, sampling and detection of no raw materials (in the control of 1), began to drop 350g of saturated sodium carbonate solution, just started dropping exothermic exothermic exotherm, control the rate of drop acceleration, so that the temperature of the reaction solution does not exceed 20 , saturated sodium bicarbonate solution drop after completion of stirring for 30min, and then static delamination, separated from the organic layer, the other layer of turbid liquid with 100g of toluene (can also be used 150g, 250g, 300g of chlorobenzene, benzene, p-toluene, etc.) extraction, layering and then 100g (can also be used 150g, 250g, 300g of chlorobenzene, benzene, p-toluene, etc.) toluene extraction once, combined with the organic layer, washed with 200g (can also be used 150g, 250g, 300g) of water, and then the organic layer depressurized to remove the solvent (60-70 degrees Celsius) to obtain (4-bromo-1-methyl-3-pyrazolyl)methanol 141.3g.
