A novel synthesis method of a triarylpyrazine derivative, in particular, a manufacturing method by which a triarylpyrazine derivative, in specific, a 2,3,5-triarylpyrazine derivative in which an aryl group at a 5-position includes a substituent having an electron-withdrawing property can be synthesized with high yield as compared to a conventional method is provided. By using a synthesis method in which a mixture including a 1-aryl-2-(methylsulfinyl)ethanone derivative, meso-1,2-diarylethylenediamine, and a dehydrogenation agent is irradiated with a microwave to be reacted, the above object is achieved.
提供了一种新的合成三芳基吡嗪衍生物的方法,特别是一种制造方法,通过这种方法,可以与传统方法相比高产地合成一种三芳基吡嗪衍生物,具体来说是一种在5-位芳基含有具有电子吸引性的取代基的2,3,5-三芳基吡嗪衍生物。通过使用一种合成方法,其中包括一种1-芳基-2-(甲基亚砜基)乙酮衍生物、meso-1,2-二芳基乙二胺和脱氢剂的混合物,通过微波辐射反应,实现了上述目标。
