Abstract
A method of synthesizing a fused heteroaromatic compound includes obtaining a first intermediate from a first compound represented by Chemical Formula 1 and a second compound represented by Chemical Formula 2, obtaining a second intermediate including a ring having a chalcogen element from the first intermediate, and obtaining a fused heteroaromatic compound by a cyclization reaction of the second intermediate.
