Condensation of 2-(cyanomethyl)benzoic acid with 2-aminobenzylamine gave 6,11-dihydro-13H-isoquino[3,2-b]quinazolin-11-one. Its oxidation in nitrobenzene led to the formation of 5,13,5',13'-hexahydro[6,6']bi[isoquino[3,2-b]quinazoline]-11,11'-dione, but in dichlorobenzene in the presence of elemental sulfur and iodine it gave the rearrangement product 6H-dibenzo[b,f][1,8]naphthyridin-5-one.
