B-(2-Amino-4-pyridinyl)boronic acid Use and Manufacturing
Intermediate 24 (1-24) 2-Amino-pyridine-4-boronic acid (1-24) 2-Amino-4-chloropyridine (3g, 23.34 mmol) was added to a mixture of bis(pinacolato)diboron (17.78 g, 70.01 mmol), 2-dicyclohexylphosphino-2', 6'- dimethoxybiphenyl (0.38 g, 0.93 mmol), tris(dibenzylideneacetone)dipalladium(0) (0.21 g, 0.23 mmol) and potassium acetate (3.89 g, 39.67 mmol) in 1, 4-dioxane (78 mL) under nitrogen atmosphere. The resulting mixture was stirred at 100 °C for 3 h. The hot reaction mixture was filtered through diatomaceous earth and washed with EtOAc. The organic layer was evaporated in vacuo. The residue was precipitated with DIPE to yield intermediate compound 1-24 as a white solid (5.84 g, quant.) that was used in the next reaction step without further purification.
