Procedure

To a mixture of tert-butyl (1-(5-bromo-2-chloropyrimidin-4-yl)piperidin-4-yl)methylcarbamate (229 mg, 0.564 mmol), pyridine-4-boronic acid (76 mg, 0.618 mmol) and Pd(Ph3P)2Cl2 (40 mg, 0.056 mmol) in dioxane (3 mL), aq. Na2CO3 (180 mg, 1.69 mmol) (1.0 mL) was added. The mixture was stirred at 100° C. for 20 h. It was concentrated in vacuo. The residue was purified by HPLC to give tert-butyl (1-(2-chloro-5-(pyridin-4-yl)pyrimidin-4-yl)piperidin-4-yl)methylcarbamate (80 mg).
