摘要: [Problem]The present invention provides an industrially advantageous production method of a 6-halogeno-3-arylpyridine derivative in which cryogenic condition is not required, production step is short, and an isomer difficult to be separated is not produced as a by-product,[Solution]A production method of a 6-halogeno-3-arylpyridine derivative represented by the general formula (III) comprising: the first step reacting a 2,5-dihalogenopyridine derivative represented by the general formula (I) with a magnesiation reagent; and the second step reacting the product obtained from the above-described first step, in the presence of a palladium compound, with a halogenoaryl derivative represented by the general formula (II).
