실험 절차

(R)-1-[2-(tert-Butyl-dimethyl-silanyloxy)-1-methyl-ethyl]-3-(4-ethyl-phenyl)-7-(4-fluoro-phenylamino)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one (100 mg, 0.18 mmol) (from Example 38f supra) in pyridine (1.5 mL) (Fisher) was treated at room temperature with hydrogen fluoride-pyridine (0.6 mL) (Aldrich) for 15 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 (R)-3-(4-ethyl-phenyl)-7-(4-fluoro-phenylamino)-1-(2-hydroxy-1-methyl-ethyl)-3,4-dihydro-1H-pyrimido[4,5-d]pyrimidin-2-one as a colorless viscous oil. (Yield 45 mg, 61%).
