실험 절차

To a flask were added 0.6 g pulverized potassium hydroxide and 15 ml dimethylsulfoxide. After adding 1.4 g of 2,2′-dipyridylamine, the mixture was stirred under nitrogen for 45 minutes, when 1.5 g 6-methyl-2-(bromomethyl)pyridine was added. After stirring for 1 hour, 35 ml of water was added and the product was extracted with 60 ml of 50% ethyl acetate, 50% hexane. The organic layer was washed with 30 ml water and the solvent was removed. The residue was purified by silica gel chromatography using 48% ethyl acetate, 48% hexane, and 4% methanol resulting in 2.0 g of an oil.
