Procedure

A mixture of 2-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (200 mg, 0.84 mmol), methanamine (277 mg, 8.4 mmol), and DIPEA (0.35 mL, 2.01 mmol) in dioxane (5 mL) was stirred at room temperature for 16 hours. It was then concentrated under reduced pressure, and the residue was treated in EtOAc. The insoluble solid was removed by filtration, and the organic solution was concentrated under reduced pressure to give the title compound.
