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.
提供了一种新颖的方法,可以在不使用卤代吡嗪衍生物的合成途径的情况下合成吡嗪衍生物,该卤代吡嗪衍生物是一种合成中间体,其吡嗪骨架被卤化。此外,提供了一种使用上述合成方法获得的吡嗪衍生物作为EL材料的发光元件、发光装置、电子装置或照明装置,具有高发射效率。在该方法中,合成了一种具有芳基或杂环芳基取代基的2-芳基吡嗪衍生物。
