Abstract

A technique that can synthesize an aromatic sodium compound easily, in a short time, and efficiently through a small number of steps is constructed. The invention comprises a step A in which, in a reaction solvent, an alkyl halide compound represented by general formula I (R¹—X¹) (wherein R¹ is an alkyl group and X¹ is a halogen atom) is reacted with a dispersion that is obtained by dispersing sodium into a dispersion solvent, thereby obtaining an alkyl sodium compound represented by general formula II (R¹—Na) (wherein R¹ is the same as R¹ of general formula I); and a step B in which, a halogenated aromatic compound represented by general formula III (R²—X²) (wherein, in the formula, R² is an aromatic group that may have a substituent that does not react with sodium, and X² is a halogen atom) is added into the reaction solvent after the step A to react with the alkyl sodium compound represented by general formula II (R¹—Na), which has been obtained in the step A, thereby performing halogen-sodium exchange and obtaining an aromatic sodium compound represented by general formula IV (R²—Na).
