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.
提供了一种新颖的三芳基吡嗪衍生物的合成方法,特别是一种制造方法,通过该方法可以比传统方法更高产地合成具有电子吸引性取代基的5位芳基的2,3,5-三芳基吡嗪衍生物。通过使用一种混合物,包括1-芳基-2-(甲基亚磺酰基)乙酮衍生物,meso-1,2-二芳基乙二胺和脱氢剂,在微波辐射下反应,实现了上述目标。
