実験手順
7′-Bromo-4-methoxy-5″-methyl-3′,4′-dihydrodispiro[cyclohexane-1,2′-naphthalene-1′,2″-imidazol]-4″-amine (Example 5, 0.2 g, 0.51 mmol), 3-chloro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (123 mg, 0.51 mmol), 3-(di-tert-butylphosphonium)propane sulfonate (0.014 g, 0.05 mmol), sodium tetrachloropalladate(II) (7.54 mg, 0.03 mmol), 2-methyltetrahydrofuran (3 mL) and aq. potassium carbonate (2.0 M, 0.769 mL, 1.54 mmol) were added to microwave vial. The vial was sealed and heated in the MW for 30 min at 130° C. The same amount of ligand and Pd-catalyst were added again and the reaction was heated in the MW for 15 min at 130° C. This procedure was repeated twice more. Water and 2-Me THF were added. The water phase was eliminated and the organic phase was washed once with brine and water. The organic phase was concentrated in vacuo. The product was purified using prep HPLC to give:
