実験手順

To a solution of 4-({[3′-(hydroxymethyl)-2,6-dimethylbiphenyl-4-yl]oxy}methyl)tetrahydro-2H-thiopyran-4-ol (0.90 g, 2.51 mmol), ethyl 3-(2-fluoro-4-hydroxyphenyl)propanoate (0.56 g, 2.64 mmol) and tributylphosphine (0.86 mL, 3.26 mmol) in tetrahydrofuran (20 mL) was added 1,1′-(azodicarbonyl)dipiperidine (0.85 g, 3.26 mmol) at room temperature with stirring, and the mixture was stirred for 10 hrs. The resulting precipitate was filtered off and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1-hexane/ethyl acetate=2/1) to give the title compound (1.24 g, yield 89%) as a colorless oil.
