Participants

Reaction Steps

To a solution of methyl 3-(4-hydroxyphenyl)propanoate (3.28 g, 18.2 mmol), [2′,6′-dimethyl-4′-(tetrahydro-2H-pyran-2-yloxy)biphenyl-3-yl]methanol (5.15 g, 16.5 mmol) and triphenylphosphine (5.63 g, 21.5 mmol) in tetrahydrofuran (100 mL) was added dropwise diethyl azodicarboxylate (40% toluene solution, 9.7 mL) at 0° C. with stirring, and the mixture was stirred at room temperature for 48 hrs. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1-hexane/ethyl acetate=3/1) to give the title compound (2.92 g, yield 37%) as a yellow oil.
