A mixture of 4-chloro-2-methyl-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrrolo[2,3-b]pyridine (296.5 mg, 1 mmol) and TBAF (5 mL, 1 M in THF, Aldrich) was refluxed overnight. The THF was removed under reduced pressure and the residue was diluted with water (5 mL). The precipitate that formed was collected, washed with water and dried (MgSO4) to afford the title compound (101 mg, 60%). 1H NMR (CD3OD) δ 7.99 (d, 1H, J=5.5 Hz), 7.06 (d, 1H, J=5.5 Hz), 6.23 (s, 1H), 2.46 (s, 3H); MS(ESI+) m/z 167 and 169 (M+H, 1 Cl)+.
