Electric Literature of 288-13-1<\/a>, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 288-13-1 name is 1H-Pyrazole, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.<\/p>\n

2a (5.Og, 73.5mmol) was added in portions to H2SO4 (35mL) while keeping the temperature below 400C, then 70% HNO3 (5.06mL, 80.6mmol) was added dropwise while maintaining the temperature below 55 0C. The mixture was then heated at 550C for 5h and cooled to 00C. The mixture was neutralized with 50% NaOH and the resulting slurry was diluted with ethyl acetate. The resulting precipitate was removed by filtration. The filtrate was separated and the organic phase was washed with water and brine, dried over MgSO4 and concentrated in vacuum. The residue was crystallized for ethanol to afford 2b (7.1g, 85.5%)<\/p>\n

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1H-Pyrazole, and friends who are interested can also refer to it.<\/p>\n","protected":false},"excerpt":{"rendered":"
