                            A straightforward single step method for the preparation and/or production of substituted quinazolines is disclosed, wherein said quinazolines preferably contain one substituent at position 4, and may contain other functional groups at various positions, such as 5, 6, 7, and/or 8 of quinazolines. In addition, the extension of this new method leads to the formation of different type of heterocyclic aromatic compounds, that include but are not limited to perimidines, anthrapyrimidin-7-ones (also known as anthrapyrimidinones), anthra[1,9:5, 10]dipyrimidines (also known as quinazoline[5,4-ef]perimidines) and benzo[e]- pyrimido[4,5,6-gh]pyrimidines.
