PROBLEM TO BE SOLVED: To provide an efficient method for producing a 2,3-dicyanonaphthalene derivative substituted at fifth to eighth positions. SOLUTION: This method for producing the 2,3-dicyanonaphthalene derivative expressed by formula (3) [wherein, R<SP>1</SP>to R<SP>4</SP>are each independently a group selected from among H, a 1-8C alkyl and a substituted or non-substituted phenyl; and R<SP>5</SP>, R<SP>6</SP>are each independently a 1-12C alkyl] is characterized by reacting a furan compound with 2,3-dicyanobenzene in the presence of a magnesium metal.
