실험 절차

Tetra-n-butylammonium fluoride (1M in tetrahydrofuran, 25.1 mL, 25.11 mmol) was added to a solution of 3-bromo-5-(2-pyridyl)-3-(trimethylsilyl)furan (4.96 g, 16.74 mmol) in tetrahydrofuran (50 mL). The reaction mixture was heated at 70° C. (bath temperature) for six hours. The reaction mixture was evaporated, and the residue was purified by flash chromatography using hexane as the eluant to give the sub-title compound as a pale brown solid (3.02 g), m/z 224, 226 (MH+).
