When 2-ethoxalylaminonaphthalene-1-carbonitrile (I) was treated with potassium cyanide and some cyanomethylene compounds, such as ethyl and methyl cyanoacetates, α-cyanoacetamide and 1-cyanoacetylpyrrolidine, the corresponding 1-aminobenzo[f]quinazolines (IVa - IVd) were obtained.
Similarly, 6-ethoxalylaminoquinoline-5-carbonitrile (II) and 2-ethoxalylaminobenzonitrile (III) gave the corresponding 1-aminopyrido[3,2-f]quinazolines (Va - Vd) and 4-aminoquinazolines (VIa - VId), respectively.
