実験手順

The resulting 1-(8-chloro-2-ethylimidazo[1,2-a]pyrazin-3-yl)-1-butanol was dissolved in ethyl acetate (4 mL) and methylene chloride (1 mL), then activated manganese (IV) oxide (3 g) was added thereto, and the mixture was heated under stirring at 60° C. for 5 hours. After being allowed to cool, the reaction mixture was filtered and washed with ethyl acetate, and then the filtrates were combined and evaporated. The resulting residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:3) to give the title compound (226 mg) as white crystals.
