A suspension of 5-bromo-2,3-dimethyl-2H-indazole (1.85 g), 4-(benzyloxy)pyridin-2(1H)-one (1.65 g), potassium carbonate (3.41 g), copper(I) iodide (1.57 g) and N,N′-dimethylethylenediamine (0.73 g) in DMSO (30 ml) was stirred at 150° C. for 3 hr. The reaction mixture was cooled to room temperature, and added to 28% aqueous ammonia, and the obtained precipitates were collected by filtration. The obtained solid was washed with water and diisopropyl ether, and dried under reduced pressure to give the title compound (1.85 g).
