실험 절차

To a tetrahydrofuran solution (11 ml) of 1-{1-[(2′-{[(1R)-3-{[tert-butyl(diphenyl)silyl]oxy}-1-methylpropyl]oxy}-3-fluorobiphenyl-4-yl)carbonyl]piperidin-4-yl}-7-chloro-3,3-dimethyl-3,4-dihydro-1,5-naphthyridin-2(1H)-one (525 mg) was added at room temperature a tetrahydrofuran solution (1 M, 1.28 ml) of tetrabutylammonium fluoride, followed by stirring for 3 hours. The reaction solution was diluted with ethyl acetate, washed sequentially with a saturated aqueous ammonium chloride solution and saturated sodium chloride solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to afford 7-chloro-1-{1-[(3-fluoro-2′-{[(1R)-3-hydroxy-1-methylpropyl]oxy}biphenyl-4-yl)carbonyl]piperidin-4-yl}-3,3-dimethyl-3,4-dihydro-1,5-naphthyridin-2(1H)-one (301 mg).
