実験手順
Add 1N solution of tetrabutylammonium fluoride (0.70 mL, 0.70 mmol) to a solution of 3-Morpholin-4-yl-1-triisopropylsilanyl-1H-indole (0.20 g, 0.56 mmol) in THF (2.0 mL). Stir at room temperature for 2 h, dilute with water, and extract with EtOAc. Wash EtOAc with saturated NaHCO3, water, dry (Na2SO4), and concentrate under vacuum. Purify the residue by flash chromatography using 20 to 80% of EtOAc in hexanes to give the title compound (0.10 g 89%). MS (ES) 203.1 (M+1)+.
