To a solution of 5-fluoro-2-((trimethylsilyl)ethynyl)pyridin-3-amine (2.22 g, 10.7 mmol) in DMF (30 mL) at 0° C. under nitrogen was added NaH (60% in mineral oil, 1.025 g, 42.7 mmol) in several portions. After stirring at RT for 2 h, the reaction mixture was poured into ice-cold water and extracted with EtOAc. The extract was dried (MgSO4), filtered, and concentrated under reduced pressure to afford 1.46 g (100%) of 6-fluoro-1H-pyrrolo[3,2-b]pyridine as a brown solid. MS (ESI): m/z=137.2 [M+1]+.
