実験手順
Into the solution of (R)-4-((R)-1-(6-(3,4-dimethoxyphenyl)-3-((2-(trimethylsilyl)ethoxy)methyl)-3H-imidazo[4,5-c]pyridin-4-yloxy)ethyl)pyrrolidin-2-one 3.08 (200 mg, 0.39 mmol) in THF (5 mL), was added 1 M solution of TBAF in THF (3.9 mL, 3.9 mmol). After reflux for 12 h, the reaction mixture was taken up with ethyl acetate (150 mL) and washed with brine, dried (MgSO4), filtered, and concentrated under reduced pressure to yield residues which were purified by silica gel column chromatography to isolate (R)-4-((R)-1-(6-(3,4-dimethoxyphenyl)-3H-imidazo[4,5-c]pyridin-4-yloxy)ethyl)pyrrolidin-2-one 3.09.
