The title compound was prepared from 5-(4-fluoro-phenyl)-cyclohexane-1,3-dione, following the procedure describing the synthesis of 2-amino-7-(4-fluoro-phenyl)-4-methyl-7,8-dihydro-6H-quinazolin-5-one (example 3/a stage 1, 2 and 3). Propionic anhydride was used instead of acetic anhydride in stage 1.
