実験手順
Triisopropylsilane (2.1 g) and trifluoroacetic acid (4.0 mL) were added to a solution of 6-iodo-2-methoxy-3-[(4-methoxybenzyl)oxy]pyridine (1 g) in chloroform (10 mL), and the mixture was stirred at 0° C. for one hour. The solvent was evaporated from the reaction solution under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=90:10→50:50) to give the title compound as a colorless powder (604 mg, 96%).
