Procedure

To 0.16 g of 1-(2-(1,4-dioxaspiro(4.5)decan-8-yl)ethyl)-7-methoxyquinoxalin-2(1H)-one, 1.5 mL of an 80% aqueous trifluoroacetic acid solution was added at room temperature, and the mixture was stirred at the same temperature for 15 minutes. Thereto was added ethyl acetate under cooling with ice, and the reaction mixture was adjusted to pH 8.0 with an aqueous saturated sodium hydrogen carbonate solution. The organic layer was separated, washed with an aqueous saturated sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to obtain 0.18 g of a brown oily substance, 7-methoxy-1-(2-(4-oxocyclohexyl)ethyl)quinoxalin-2(1H)-one.
