Procedure
By the same method as in Example 1,5-bromo-2,4′-bipyridine was prepared. The resulting 5-bromo-2,4′-bipyridine (7.0 g) was dissolved in N,N-dimethylacetamide (15 ml), followed by addition of copper (I) cyanide (2.8 g), for agitation at 140° C. for 3 hours. After the reaction solution was cooled, aqueous 25% NaOH solution (10 ml) was added to deposit a crystal, which was filtered and recovered, to obtain the object substance (4.5 g; yield of 83%).
