Quinoxaline 3- cyano-, preparation

Cyano derivatives of (18) are prepared by reaction of o-phenylenediamine with o-CcH4(CO)2N(CH2) COC(CN)=NC6H4NMe2-p. Hydrolysis of the latter compounds give intennediates of the type o-C H4(CO)2N(CH2) COCOCN which on condensation with o-phenylenediamine yield 3-phthalimidoalkylquinoxalin-2-ones. 6,7-Disubstituted quinoxalines have been prepared from 2,4-diazido-1,5-dinitrobenzene (19), which on pyrolysis is converted into 2-azido-... [Pg.111]
