実験手順
To 5-Methyl-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (12, 0.160 g, 0.55 mmol) in tetrahydrofuran (3.0 mL) was added tetra-n-butylammonium fluoride (0.145 g, 0.55 mmol). The reaction was stirred for 1 hour at room temperature. The reaction was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 3% methanol in dichloromethane to provide light yellow solid (13, 0.07 g, 95%).
