A series of 3-{4-[4-(4-aryalazo)-benzenesulfonyl]-phenyl}-2-phenyl-3H-quinazolin-4-one derivatives (3) have been obtained by a reaction of a various coupling agents with diazonium salt containing 4-oxo-quinazolin moiety (2). The diazonium salt (2) is obtained by the reaction of 4-(2- phenyl-4-oxo-3-quinazolinyl)-4’-aminodiphenylsulfone with NaNO2 and HCl. The product is characterized by spectral and analytical data. Most of the tested compounds show promising dyeing properties.
