Synthetic method of nitrogen-containing heterocyclic compound

The invention relates to a synthetic method of a nitrogen-containing heterocyclic compound. The method comprises the following step: in a solvent, reacting an aryl carbonyl compound with aryl trifluoroborate in the presence of a palladium catalyst, a nitrogen-containing ligand and an accelerator to further prepare the nitrogen-containing heterocyclic compound. The method is simple in reaction, simple and convenient to operate and high in yield, is a totally new synthetic method of a nitrogen-containing heterocyclic compound, provides a new synthetic route for preparation of the type of compound and has good scientific research value and industrialization potency.
