Reaction Steps

A mixture of 2-cyclopropyl-6-iodo-3-methylimidazo[1,2-a]pyridine (1482 mg), 4-(benzyloxy)pyridin-2(1H)-one (1000 mg), copper iodide (946 mg), N,N′-dimethylethylenediamine (0.534 ml), potassium carbonate (2061 mg) and DMSO (13 ml) was heated 110° C. for 1 h under microwave irradiation. The residue was quenched with 28% NH3 solution, and extracted with EtOAc/THF. The organic layer was separated, washed with water and brine, dried over MgSO4, passed through silica gel pad (EtOAc only) and concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/MeOH) and recrystallized from EtOH (80 ml) to give the title compound (1027 mg) as an off-white solid.
