tert-Butyl 3-(5-bromopicolinamido)propanoate (1.0 g, 3.0 mmol), 2-formylphenylboronic acid (547 mg, 3.6 mmol), Pd(dppf)Cl2 (249 mg, 0.3 mmol), and K2CO3 (840 mg, 6.1 mmol) were dissolved in 1,4-dioxane (20 mL) and water (5 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.
