実験手順

To 8 mL of a dioxane suspension containing 0.25 g of 1-(2-(8-hydroxy-1,4-dioxaspiro(4.5)decan-8-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one, 3 mL of an 80% aqueous trifluoroacetic acid solution was dividedly added at room temperature, and the mixture was stirred for 5 hours and 15 minutes. An aqueous saturated sodium hydrogen carbonate solution was added with the reaction mixture, and then added with ethyl acetate and sodium chloride. The organic layer was separated, and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue thus obtained was purified by silica gel column chromatography [eluent; hexane:ethyl acetate 1:3] to obtain 0.10 g of a colorless oily substance, 1-(2-(1-hydroxy-4-oxocyclohexyl)ethyl)-7-methoxyquinoxalin-2(1H)-one.
