Participants

Reaction Conditions

Reaction Steps

0.14 g of 1-bromo-4-nitrobenzene, 0.22 mL of tributylamine and 5.2 mg of palladium acetate were added to 2.0 mL of N,N-dimethylacetamide solution containing 0.15 g of tert-butyl 2-(benzamido)-4-vinylbenzoate at room temperature and stirred under nitrogen atmosphere at 110° C. for 1 hour and 20 minutes. After the reaction mixture was cooled to room temperature, 10% citric acid aqueous solution and ethyl acetate were added. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with 10% citric acid aqueous solution, a saturated sodium thiosulfate aqueous solution and a saturated sodium chloride aqueous solution sequentially, and the solvent was evaporated under reduced pressure. The obtained residue was purified with silica gel column chromatography [Flash Tube 2008 manufactured by Trikonex Company, eluent; hexane:ethyl acetate=4:1]to obtain 0.15 g of tert-butyl 2-(benzamido)-4-((E)-2-(4-nitrophenyl)vinyl)benzoate as yellow solid.
