What are the synthesis methods of 4,5-dichloro-2-thiophenesulfonamide?

To prepare 4% 2C5-difluoro-2-nitrobenzonitrile, there are various methods. One common method is to use benzonitrile as the starting material, introduce fluorine atoms by halogenation reaction, and introduce nitro groups at an appropriate time. This requires the selection of appropriate halogenating reagents, such as fluorine-containing halogenating agents, under specific reaction conditions, halogenate the specific position of benzonitrile, and then add nitro groups through nitrification reaction. However, this process needs to control the reaction check point and the degree of reaction.

Second, benzene derivatives containing nitro groups can be prepared first, and then halogenated to introduce fluorine atoms. First, benzene is obtained by a suitable nitration method to obtain nitrobenzene compounds, and then it is halogenated to make the fluorine atom connect to the target position. This also requires detailed consideration of the reaction conditions and reagent activity to ensure that the reaction follows the expected direction.

Or it can be obtained by other compounds with similar structures through functional group conversion, rearrangement, etc. For example, some compounds containing nitrile groups and halogen atoms can be rearranged and functional groups converted to 4% 2C5-difluoro-2-nitrobenzonitrile under appropriate reaction conditions.
