6270-63-9, 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. 6270-63-9 name is Pyrazin-2(1H)-one, 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.
Using the same procedure described in example 1 using 1-(4-amino-3-fluoro-phenyl)-1H-pyrazin-2-one (prepared from 2-fluoro-4-iodoaniline by reaction with 1H-pyrazin-2-one, Cu(I)I, N,N’-dimethylethylenediamine and cesium carbonate in dioxane at 120 C.), the title compound was obtained as a white solid (15 mg). MS: 508.0 (M+H)+
At the same time, in my other blogs, there are other synthetic methods of this type of compound, Pyrazin-2(1H)-one, and friends who are interested can also refer to it.
