실험 절차
Dissolve 3.35 g of cyclopropyl(3-pyridyl)methanol, the compound obtained in the preceding step, in 75 ml of dioxane and add 13.66 g of manganese dioxide. After 4 hours of stirring under reflux, filter the reaction medium while hot through Celite. The organic solution yields, after evaporating under vacuum, a residue which is purified by chromatography on a silica column, using a mixture of cyclohexane and ethyl acetate (1:1 V/V) as eluent, to obtain cyclopropyl 3-pyridyl ketone.
