Reaction Conditions

Reaction Steps

Triethylsilane (5 mL) and trifluoroacetic acid (5 mL) were sequentially added to (6-methoxy-5-methylpyridin-2-yl)[4-(methylsulfanyl)phenyl]methanol obtained in Reference Example 1-36(2) (2.13 g), and the mixture was stirred at 60° C. for four hours. The reaction solution was poured into saturated aqueous sodium bicarbonate, followed by extraction with chloroform. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and filtered. The solvent was then evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=9:1→4:1→2:1) to give the title compound as a colorless oil (1.69 g).
