反応手順

To a solution of 5-(2-{[tert-butyl(dimethyl)silyl]oxy}ethyl)-4-chloro-5H-pyrrolo[3,2-d]pyrimidine (560 mg) in tetrahydrofuran (1.7 mL), was added tetrabutylammonium fluoride (1M tetrahydrofuran solution) (2.69 mL) under ice-cooling, and the mixture was stirred for 4 hrs. The reaction mixture was diluted with water (20 mL) and extracted with ethyl acetate (30 mL×3). The organic layer was washed with saturated brine (30 mL×3) and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was subjected to silica gel column chromatography (silica gel, eluent:ethyl acetate/methanol=10/0→9/1). The object fraction was concentrated under reduced pressure and dried to give the title compound (391 mg) as a white solid.
