実験手順

To a stirred solution of 2-propyl-2-(1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine-5-carbonyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (0.415 g, 0.809 mmol) in THF (7.5 mL) at ambient temperature under nitrogen was added TMAF (0.753 g, 8.09 mmol). The reaction mixture was stirred for one hour, then diluted with saturated aqueous NaHCO3 (30 mL) and water (15 mL) and extracted with EtOAc. The combined organic extracts were washed with brine, dried (MgSO4), filtered, and concentrated in vacuo to a pale yellow gum. Purification by chromatography (silica, 50 to 100% EtOAc in hexanes) gave 2-propyl-2-(1H-pyrrolo[2,3-b]pyridine-5-carbonyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (0.247 g, 0.692 mmol, 86%) as a colourless foam.
