Reaction Steps

4-propyl-1-{[1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]methyl}pyrrolidin-2-one x256 (0.7 g, 1.7 mmol) is dissolved in absolute THF (7 ml). A 1 M solution of tetrabutylammonium fluoride in THF (1.7 M, 1 eq) is added. The obtained solution is stirred for 10 min at room temperature and poured into a mixture of ether (100 ml) and water (20 ml). The organic phase is separated, dried with anhydrous sodium sulfate, and evaporated. The residue is purified by chromatography on silicagel (dichloromethane/isopropanol) to yield 0.43 g of 4-propyl-1-(1H-pyrrolo[2,3-b]pyridin-5-ylmethyl)pyrrolidin-2-one 241.
