実験手順

A solution of (±)-1-[trans-3-(tert-butyl-dimethyl-silanyloxy)-cyclopentyl]-3-(4-ethyl-phenyl)-7-(4-fluoro-phenylamino)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one (47 mg, 0.08 mmol) in pyridine (1 mL) (Fisher) was treated at room temperature with hydrogen fluoride-pyridine (0.6 mL) (Aldrich) for 20 minutes. The reaction mixture was quenched with 1 N aqueous hydrochloric acid at 0° C., then extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (50% ethyl acetate in hexanes) to give (±)-3-(4-ethyl-phenyl)-7-(4-fluoro-phenylamino)-1-(trans-3-hydroxy-cyclopentyl)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one as a white solid. (Yield 32 mg, 87%).
