A 40 mL vial was charged with 2-chloro-N-methoxy-N-methyl-isonicotinamide (800 mg, 3.86 mmol), bis-(4-methoxy-benzyl)-amine (1.49 g, 5.80 mmol), 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene-(1,4-naphthoquinone)palladium (0) dimer (126 mg, 0.097 mmol), sodium tert-butoxide (519 mg, 5.41 mmol), and dioxane (12 mL). The vial was sealed, warmed to 110° C., and stirred overnight. The next day, the reaction was filtered through Celite, dry loaded onto silica gel, and purified via automated silica gel chromatography to generate 795 mg (47%) of the protected aminopyridine.
