Synthesis of 9H-Indeno [1, 2-b] Pyrazine and 11H-Indeno [1, 2-b] Quinoxaline Derivatives in One-step Reaction from 2-Bromo-4-chloro-1-indanone
Abstract
The reaction of 2-bromo-4-chloro-1-indanone with 2,3-diaminomaleonitrile, benzene-1,2-diamine and 4-methylbenzene-1,2-diamine in glacial acetic acid gave 8-chloro-9H-indeno[1,2-b]pyrazine-2,3-dicarbonitrile, 1-chloro-11H-indeno[1,2-b]quinoxaline and 1-chloro-7-methyl-11H-indeno[1,2-b]quinoxaline, respectively, in good yield.
