反応手順
Copper(I) iodide (102 mg) was added to a mixture of picolinic acid (66.1 mg), 4-(2-aminopyridin-3-yl)phenol (500 mg), tripotassium phosphate (1710 mg), 1-iodo-3-methylbenzene (703 mg) and DMSO (8 ml). The mixture was stirred at 130° C. under nitrogen for 5 hr. Activated carbon was added and the insoluble solid was removed by filtration through NH-silica gel/Celite pad (eluted with EtOAc). Water was added and the extracted organic layer was washed with brine. Silica-gel was added to the organic layer and the volatiles were removed in vacuo. The mixture supported on silica-gel was purified by column chromatography (NH-silica gel, eluted with EtOAc in hexane) to give the title compound (511.5 mg) as a yellow solid.
