An efficient and high yielding protocol is reported for the synthesis of new class of 4-anilinoquinolino-quinazoline hybrids. The target compounds were prepared first by the reaction of 2-aminobenzamide with 2-chloroquinoline-3-carbaldehydes. After oxidation and chlorination, the key 2-quinolyl-4-chloroquinazolines were converted to the corresponding 2-(2-arylaminoquinolyl)-4-arylaminoquinazolines and N-heteroaryl-2-(2-(heteroarylamino)quinolin-3-yl)quinazolin-4-amines.
