반응 단계
To a solution of 2-bromo-5-iodo-3-methylpyridine (1.5 g) in DMF (15 mL) was added palladium(II) acetate (56.5 mg) and tri-o-tolylphosphine (230 mg) and diisopropylethylamine (3.5 mL), and ethyl acrylate (1.09 mL). The mixture was heated at 90° C. for 1 hour. Resulting mixture was poured into water and extracted with AcOEt. The organic layer was washed with water and brine, and dried over Na2SO4, and the solvent was removed in vacuo. Residual brown oil was purified by silica gel column chromatography eluted with AcOEt and hexane (1:4-1:2) to give ethyl (2E)-3-(6-bromo-5-methyl-3-pyridyl)acrylate (1.00 g) as pale yellow powder.
