실험 절차
Stir a solution of 1-(2,4-dihydroxy-3-propyl-phenyl)-ethanone (1.75 g, 9 mmol), 3-[(4-hydroxymethyl-phenyl)-(tetrahydro-pyran-2-yloxy)-methyl]-benzonitrile (2.9 g, 9 mmol), toluene (10 mL), and dichloromethane (10 mL) at −20° C. Add 1,1′-(azodicarbonyl)dipiperidine (4.5 g, 18 mmol) followed by tributylphosphine (4.5 mL, 18 mmol) and allow the resulting yellow solution to stir at room temperature overnight. Concentrate the resulting thick reaction mixture and dilute with ether (50 mL). Cool the slurry to 0° C. with stirring, for 30 minutes. Filter the reaction mixture, concentrate, and purify via silica chromatography eluting with 1:1 hexanes:(5:4:1 hexanes:dichloromethane:ethyl acetate) to give the title compound (3 g, 67%), as an orange thick oil. LCMS (m/z) 498 M−1.
