Diphenylmethane (I) is nitrated to the tetranitro derivative (II) employing KNO3 in concentrated H2SO4. Oxidation of the diarylmethane (II) with CrO3 in boiling HOAc provides benzophenone (III). Cyclization of (III) under reductive conditions gives rise to the diamino acridone (IV), which is further acylated by 3-chloropropionyl chloride (V) to the bis-chloropropionamide (VI). Nucleophilic substitution of the chloride groups of (VI) with pyrrolidine (VII) furnishes the bis-pyrrolidino derivative (VIII). Chlorination of acridone (VIII) with POCl3 yields the chloroacridine (IX). This is finally condensed with 4-(dimethylamino)aniline (X) to produce the title compound.
