To a microwave vial was added a stir bar, 6-chloro-pyridine-2-carboxylic acid {3-[(pyridine-2-carbonyl)-amino]-adamantan-1-yl}-amide (Intermediate 4, 20 mg, 0.05 mmol), copper (II) acetoacetonate (20 mg), DMA (1 mL), imidazole (50 mg, 0.73 mmol) and cesium carbonate (60 mg, 0.15 mmol). The mixture was heated at 180° C. under microwave irradiation for 15 minutes. Solvent was removed in a high performance solvent evaporation system HT-4X (Genevac, Inc., supra). The residue was dissolved in DCM (2 mL), washed with aq. 1N NaOH (2 mL), and water (2×2 mL). After removing the solvent, the residue was purified on a RP-HPLC/MS system (Gradient: acetonitrile in water with a cycle time of 5 min. Flow rate: 100 mL/min. Mobile phase additive: 25 mM of ammonium acetate. Column: Inertsil® C8, 30×50 mm, 5 μm particle size (GL Sciences, Tokyo, Japan) to afford 4.5 mg of the title compound, 6-imidazol-1-yl-pyridine-2-carboxylic acid {3-[(pyridine-2-carbonyl)-amino]-adamantan-1-yl}-amide. ESI-MS m/z: 443.5 (M+H)+.
