Reaction Steps

1-Methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (80.7 mg), bis(tri-tert-butylphosphine)palladium (0) (9.91 mg) and a 1 N potassium phosphate solution (388 μL) were added to a solution of tert-butyl 5-bromopyridine-2-carboxylate (50 mg) in 1,4-dioxane (2 mL). After replacement with nitrogen, the mixture was heated to 100° C. and stirred for eight hours. The reaction solution was cooled to room temperature, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound as a mixture (81 mg).
