Abstract

Dibenzo[b,f][1,4]diazocine-6,11-diones (1) were converted to the corresponding 6,11-disubstituted amino derivatives (3) when treated with secondary amines in the presence of titanium tetrachlorideanisole complex. Formation of the (benzimidazol-2-yl)benzamides (4) as the side products was observed in the case of substituted 1.
