실험 절차

Combine 7-[(Triisopropylsilanyl)-ethynyl]-imidazo[1,2-a]pyridine (3.23 g, 10.82 mmol) and tetrabutylammonium fluoride (1.19 mL, 1.19 mmol, 1.0 M in THF) in THF (5 mL). Stir the mixture at room temperature for 40 minutes, then concentrate in vacuo to a black oil. Purify by column chromatography (ethyl acetate) to afford product (1.10 g, 71%). MS(ES), m/z 143.1 (M+1).
