실험 절차

A mixture of 4-bromomethyl-3-nitrobenzoic acid benzyl ester (2.06 g, 5.88 mmol) and triphenylphosphine (1.54 g, 5.87 mmol) in DMF (10 mL) was heated at 100° C. for 1 h. To this solution was then added 3-(4-formyl-3,5-dimethylphenyl)-acrylic acid methyl ester (1.28 g, 5.86 mmol) (Example 1-60, step C) and potassium carbonate (1.63 g, 11.8 mmol) and the mixture was stirred for at 100° C. 18 h. The mixture was poured into ethyl acetate and extracted with water once and brine five times. The organic layer was dried, filtered, and solvent removed under reduced pressure. The residue was purified by chromatography using a 0-40% gradient of heptane/ethyl acetate to give the title compound.
