Embodiment 1

[0135] Embodiment 1: the synthesis of compound 1-28

[0136] (Synthesis of intermediate M1)

[0137] The synthetic route of intermediate M1 is as follows:

[0138]

[0139] Add 7.0g (30mmol) 5,6-dicyanoacenaphthylene-1,2-dione, 5.7g (30mmol) 5-bromo-2,3-diaminopyrazine and 100mL glacial acetic acid in a clean 250mL single-necked bottle , gradually warmed to reflux and reacted overnight under reflux. After the reaction was completed, the heating was stopped, and the system cooled down by itself. The reaction solution was poured into 1L of ice water, collected by suction filtration, squeezed and dried, and further purified by column chromatography (350 mesh silica gel, eluent: petroleum ether: dichloromethane = 2:3 (V / V)) Afterwards, 9.4 g of yellow solid was obtained, and the yield was 82%.
