실험 절차

A mixture of 4-((4-chlorobenzyl)oxy)pyridin-2(1H)-one (108 mg), 6-bromo-2-cyclopropyl-3-methylimidazo[1,2-b]pyridazine (150 mg), N,N′-dimethyl-1,2-ethanediamine (81 mg), CuI (87 mg), potassium carbonate (190 mg) and DMSO (3 ml) was heated at 150° C. for 1 h under microwave irradiation. The mixture was poured into 28% NH3 solution, and extracted with EtOAc. The organic layer was separated, washed with water and brine successively, dried over MgSO4, concentrated in vacuo, and purified by column chromatography (hexane/EtOAc), followed by crystalization from EtOAc-hexane to give the title compound (52.3 mg) as pale yellow crystals.
