[0078]Table 1. Preparation Example Product Data Summary:
[0079]
[0080]1,2-benzoquinone or pyroxal or phenanthrene or 1,10-phenanthridine-5,6-diketone and 2-bromipate-3,4 diamine and / or 5-bromipate-3, 4 Diamine is added to acetic acid in accordance with the ratio of molar ratio 1: 1, and after cooling to room temperature, the reaction liquid is poured into water, filtered, washed with water and methanol, and the resulting filter cake is vacuum dry, resulting in 1 - and / or 4-bromoic benzopyrazine.
[0081]1- and / or 4-bromine benzopyridine and the intermediate reactants were reacted with a one-step reaction or two steps in nitrogen in nitrogen, and potassium carbonate, four in the water, and water in nitrogen and water according to the molar ratio 1: 1.1. (Trobenzylphosphine) palladium refluxed 24 hours, then cooled to room temperature, filtered to room temperature, and water was added to the filtrate, and the organic phase was extracted with dichloromethane, separated from the organi...
