Procedure

1-[3-{[Tert-butyl(dimethyl)silyl]oxy}-2-(methoxymethoxy)propyl-7-methoxyquinoxalin-2(1H)-one (863 mg, 2.11 mmol) was dissolved in tetrahydrofuran (10 ml). Tetrabutyl ammonium fluoride (1M tetrahydrofuran solution; 2.74 ml, 2.74 mmol) was added to this solution under cooling on ice, and the mixture was stirred for 3 hours. The reaction solution was diluted with dichloromethane and washed with saturated sodium bicarbonate water. After drying with anhydrous sodium sulfate, the solvent was removed under reduced pressure and the residue was purified by silica gel column chromatography (chloroform/methanol) to yield 495 mg (80%) of the title compound in the form of a yellowish solid.
