Aniline derivatives containing specific substituents and ethyl cyanoacrylate compounds are selected to form aminoenonitrile intermediates under acid catalysis. The strength and dosage of this acid need to be precisely controlled. If it is too strong and too much, it is easy to cause substrate decomposition; if it is too weak and too little, the reaction will be slow.
Subsequently, this intermediate undergoes a molecular inner ring reaction under heat or light induction to form the basic skeleton of the target product. After appropriate modification, 3 - (diethylamino) -7-oxo-7H-chromono [3 ', 2': 3,4] pyridino [1,2-a] benzimidazole-6-formonitrile. < Br >

Then go through subsequent cyclization, oxidation and other steps to achieve the purpose of synthesis. Each method has its own advantages and disadvantages. In actual operation, the optimal method should be selected according to the availability of raw materials, cost, and difficulty of reaction conditions.
