Paragraph 0094-0099, (2021/04/21)
The invention provides nitrogen-containing aromatic heterocyclic diamine and a preparation method thereof. The nitrogen-containing aromatic heterocyclic diamine has a structure as shown in a formula (III); and in the formula (III), X, Y and Z are independently selected from C or N, at least two of X, Y and Z are C, and R0 is selected from NH2 or a group shown in the specifiation. Compared with the prior art, the preparation method provided by the invention has the advantages that the nitrogen-containing aromatic heterocyclic diamine with the specific structure is prepared by adopting a one-step method, the route is simple, the operation is simple and convenient, the reaction is efficient (the conversion rate is high and the selectivity is good), the post-treatment is convenient, the reaction substrate is suitable for broad spectrum, and the preparation method is suitable for industrial mass production.
