5-Trimethylsilanylethynyl-1H-pyrrolo[2,3-b]pyridine (26, 0.235 g, 1.10 mmol) was dissolved in 16 mL of methanol, and potassium carbonate (0.0152 g, 0.110 mmol) was added. The reaction was stirred for 2 hours at room temperature, then concentrated under vacuum, and the residue was dissolve in dichloromethane, dried over sodium sulfate. Solids were filtered out and the filtrate was concentrated under vacuum. The crude material was purified by silica gel flash chromatography, eluting with ethyl acetate and hexane. The appropriate fractions were combined and the solvents removed under vacuum to provide the desired compound as a solid (27, 0.155 g). MS (ESI) [M+H+]+=143.3.
