Procedure

A mixture of 4-((4-chlorobenzyl)oxy)pyridin-2(1H)-one (26.2 mg), 6-bromo-2-cyclopropyl-3-methylimidazo[1,2-a]pyrazine (42.1 mg), N,N′-dimethyl-1,2-ethanediamine (19.63 mg), CuI (21.2 mg), potassium carbonate (46.2 mg) and DMSO (1 ml) was heated at 150° C. for 1 h under microwave irradiation. The mixture was poured into 28% NH3 solution at room temperature 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) to give the title compound (19.1 mg) as pale yellow crystals.
