Preparation method of 2-aminosulfonyl-N, N-dimethyl nicotinamide

The invention provides a preparation method of 2-aminosulfonyl-N, N-dimethyl nicotinamide. The preparation method comprises the following steps: synthesizing 2-chlorine-N, N-dimethyl nicotinamide by taking 2-cyano-5-dimethylamino-2, 4-pentadienyl dicarboxamide and hydrochloric acid gas as raw materials, and reacting at the temperature of between 0 and 100 DEG C to synthesize the 2-chloro-N, N-dimethyl nicotinamide. Furthermore, the preparation method provided by the invention also comprises the step of sequentially synthesizing the 2-sulfydryl-N, N-dimethyl nicotinamide, the 2-chlorosulfonyl-N, N-dimethyl nicotinamide and the 2-aminosulfonyl-N, N-dimethyl nicotinamide by taking the 2-chloro-N, N-dimethyl nicotinamide as a raw material. According to the preparation method of the 2-aminosulfonyl-N, N-dimethyl nicotinamide, provided by the invention, the novel preparation method is provided by taking the 2-cyano-5-dimethylamino-2, 4-pentadiene dicarboxamide as an initial raw material, and the preparation method is relatively short in synthetic route, relatively high in yield and relatively low in cost.
