Reference of 2075-45-8<\/a>, The chemical industry reduces the impact on the environment during synthesis 2075-45-8, name is 4-Bromo-1H-pyrazole, I believe this compound will play a more active role in future production and life.<\/p>\n

4-bromopyrazole (15.6 g, 0.1 mol), ethyl iodide (10.9 g, 0.1 mol), tetrabutylammonium iodide (3.7 g, 0.01 mol) at room temperature,Dissolved in 5 ml of dimethyl sulfoxide (DMSO), and added with sodium hydroxide solution [sodium hydroxide solution: a solution obtained by dissolving 4.4 g (0.11 mol) of sodium hydroxide in 5 ml of water],The reaction is exothermic. After the addition is completed, it is stirred at room temperature overnight, diluted with water and diluted with dichloromethane.Drying, concentration and distillation under reduced pressure gave 16.8 g of 1-ethyl-4-bromo-1H-pyrazole.The yield was 96.0%.<\/p>\n

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, 4-Bromo-1H-pyrazole, other downstream synthetic routes, hurry up and to see.<\/p>\n
