Synthesis of some novel 2(1H)-quinazolinones and 2-thioxo analogues from newly synthesised 1-acyl-3-alkoxyphenylureas and thioureas
A convenient route for the synthesis of new 2(1H)‐quinazolinones (IIc—h) and 2(1H)‐quinazolinethiones (IIi—j) is discussed. It involves the cyclodehydration of 1‐acyl‐3‐(alkoxyphenyl)ureas (Ic—h) and the corresponding thioureas (Ii—j) in polyphosphoric acid. Elucidation of structures of the isolated...

Elucidation of structures of the isolated products have been proved in the light of their elemental analysis and spectroscopic data. |
