Reaction Steps
Ethyl 3-(5-bromopicolinamido)propanoate (1.0 g, 3.3 mmol), (2-formyl-5-methoxyphenyl)boronic acid (777 mg, 4.3 mmol), Pd(dppf)Cl2 (364 mg, 0.5 mmol), and K2CO3 (918 mg, 6.6 mmol) were dissolved in 1,4-dioxane (20 mL) and water (5 mL) and heated to 80° C. After 2 h the resulting mixture was cooled to room temperature, diluted with EtOAc washed with water and brine, dried (Na2SO4), concentrated and purified via column chromatography to yield the title compound.
