Synthesis of ( Z )-2-(4-(Arylimino)-3,4-Dihydroquinazolin-2(1 H )-Ylidene)-1 H- Indene-1,3(2 H )Dione Using 2-Amino- N′ -Aryl-Benzimidamides as a Starting Material

Abstract

The reaction between 2-amino-N′-arylbenzimidamide derivatives (3a–g) and 2-dicyanomethyleneindan-1,3-dione (4, CNIND) is described. The product that was obtained in moderate to good yields via CT-complexation is identified as (Z)-2-[4-(arylimino)-3,4-dihydroquinazolin-2(1H)-ylidene]-1H-indene-1,3(2H)-dione (5a–g).
