4-(2-Hydroxyethoxy)-6,6'-dimethyl-2,2'-bipyridine (24) (1.0 g, 4.1 mmoles) was dissolved in dry pyridine (20 ml), and benzoyl chloride (0.63 g, 4.5 mmoles) was added. After 30 minutes chloroform (50 ml) was added and the solution was extracted with saturated sodium bicarbonate. The chloroform phase was dried and the solvent was evaporated and coevaporated with dry toluene. The product was purified by means of flash chromatography (silica, 0-50% methanol/dichloromethane).
