    Abstract: A novel method in which a pyrazine derivative is synthesized without a synthetic pathway of a pyrazine halide derivative, which is a synthetic intermediate, whose pytazine skeleton is halogenated is provided. Furthermore, a light-emitting element, a light-emitting device, an electronic device, or a lighting device with high emission efficiency by using a pyrazine derivative obtained by the above synthesizing method as an EL material is provided. In the method, a pyrazine derivative is synthesized without a synthetic pathway of a pyrazine halide derivative, which is a synthetic intermediate, whose pytazine skeleton is halogenated. Specifically, a 2-arylpyrazine derivative having an aryl group or a heteroaryl group as a substituent is synthesized.
