Procedure

Ethyl 3-(5-bromopicolinamido)propanoate (800 mg, 2.7 mmol), 2-formylphenylboronic acid (518 mg, 3.5 mmol), Pd(dppf)Cl2 (217 mg, 0.27 mmol), and K2CO3 (734 mg, 5.3 mmol) were dissolved in 1,4-dioxane (16 mL) and water (4 mL) and heated to 80° C. After 3 h the resulting mixture was cooled to room temperature, diluted with EtOAc washed with water and brine, dried (Na2SO4), dry-packed onto silica gel and purified via column chromatography to yield the title compound.
