実験手順
Diethylazodicarboxylate (1.13 mL 5.83 mmol) was added dropwise to a solution of (E)-3-(3-acetoxy-4-methoxy-phenyl)-N-(3-hydroxy-phenyl)-acrylamide (0.763 g, 2.33 mmol), (5-methyl-furan-2-yl)-methanol (0.392 g, 3.5 mmol) and triphenylphosphine (1.53 g, 5.83 mmol) in dry THF (20 mL) at 0° C. The resulting solution was allowed to reach RT and stirred for 16 hrs. The reaction mixture was then diluted with DCM and washed with water, aqueous hydrochloric acid, and brine. The organic layer was then dried over sodium sulphate and evaporated. The resulting raw material was taken up, without further purification, with a 3N methanolic solution of hydrochloric acid (5 mL-15 mmols) and stirred at RT for 16 hrs, concentrated under reduced pressure, taken up with solvent an re-evaporated (3 times with MeOH and once with acetone) to give a residue that was purified by silica gel column chromatography (eluant DCM/MeOH 98/2) to obtain 15 mg of the title (E)-3-(3-hydroxy-4-methoxy-phenyl)-N-[3-(5-methyl-furan-2-ylmethoxy)-phenyl]-acrylamide.
