SYNTHETIC METHOD OF FUSED HETEROAROMATIC COMPOUND AND FUSED HETEROAROMATIC COMPOUND AND INTERMEDIATE THEREFOR AND SYNTHETIC METHOD OF INTERMEDIATE

摘要

The present invention relates to a synthesis method of a fused heteroaromatic compound, which comprises the steps of: reacting a compound represented by chemical formula 1 with a metal alkyl chalcogenide in the presence of a palladium catalyst and a tertiary phosphine catalyst to obtain a first intermediate represented by chemical formula 2; obtaining a second intermediate represented by chemical formula 3 from the first intermediate; obtaining a third intermediate from the second intermediate and a compound represented by chemical formula 4; obtaining a fourth intermediate including a chalcogen-containing ring from the third intermediate; and performing a cyclization reaction of the fourth intermediate to obtain a fused heteroaromatic compound. In addition, the present invention relates to a fused heteroaromatic compound obtained by the synthesis method, an intermediate thereof, and a synthesis method of the intermediate.
