5-Bromo-1-((6-methoxypyridin-3-yl)methyl)-N-methyl-2-oxo-1,2-dihydropyridine-3-carboxamide (150 mg, 0.426 mmol), cobalt carbonyl (36.4 mg, 0.106 mmol), DMAP (104 mg, 0.852 mmol), palladium (II) acetate (4.78 mg, 0.021 mmol), cyclopropanamine (24.32 mg, 0.426 mmol) and xantphos (12.32 mg, 0.021 mmol) were added to a microwave vial. The vial was sealed, THF (3.3 mL) added and the reaction mixture was heated in a Biotage Initiator microwave at 80° C. for 30 min. The resulting mixture was diluted with water (20 mL) and extracted with ethyl acetate (20 mL). The organic layer was dried, concentrated under vacuum and purified by MDAP (High pH), the appropriate fractions were combined and concentrated under vacuum. The resulting product was loaded in DCM and purified by Biotage Isolera SNAP 10 g silica flash chromatography using a gradient of 0-60% cyclohexane/ethyl acetate. The product containing fractions were combined and concentrated under vacuum to give the product (64 mg) as a white solid.
