The synthesis of 6‐nitro substituted 3‐aryl‐2‐methyl‐4(3H)‐quinazolinones from readily available starting materials, such as isatoic anhydride, is described. One of these, 3‐phenyl‐2‐methyl‐4(3H)‐quinazolinone, has been utilised to prepare a range of styryl disperse dyes for polyester. Novel azo disperse dyes based on 6‐nitro‐3‐(m‐diethylaminophenyl)‐2‐methyl‐4(3H)‐quinazolinone as coupling component are reported. The application properties of the dyes on polyester and their fastness properties have been evaluated, with the latter being disappointing.
