Reaktionsschritte

To 5-chloro-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (79, 1.40 g, 4.53 mmol) in tetrahydrofuran (15 mL) was added tetra-n-butylammonium fluoride (1.42 g, 5.43 mmol). The reaction mixture was stirred at room temperature for 10 minutes. The reaction mixture was concentrated and isolated by silica gel column chromatography eluting with 30% ethyl acetate in hexane to give the compound (80, 0.40 g. 58% over 2 steps). MS (ESI)[M−H+]−=153.1.
