Procedure

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-{[(2-nitrophenyl)sulfonyl]amino}phenyl)propanoate (1.05 g, 2.64 mmol) and tributylphosphine (0.86 mL, 3.26 mmol) in tetrahydrofuran (15 mL) was added 1,1′-(azodicarbonyl)dipiperidine (0.85 g, 3.26 mmol) under stirring at room temperature, and the mixture was stirred for 10 hr. 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 (1.71 g, yield 92%) as a pale-yellow amorphous powder.
