Procedure
The mixture was then cooled to room temperature and hydrolyzed with 50 cc of water. The oil layer was separated, and the aqueous phase was extracted with 50 cc additional xylene. The oil layer and extract were combined and distilled to give 82.4 g of unreacted 4-cyclohexylmethylpyridine (0.47 mole) and 9.0 g (0.03 mole) of 4,4'-di-(cyclohexylmethyl)-2,2'-bipyridyl boiling at 273°-276° C. at 2.5 mm Hg. The yield of 2,2'-bipyridyl product was calculated at 43.3% based on the amount of 4-cyclohexylmethylpyridine consumed. This 2,2'-bipyridyl compound (recrystallized from isopropanol) gave a melting point of 117°-119° C.
