Versuchsvorschrift

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-bromo-4,4-dimethylcyclohex-1-ene (609 mg) and DMSO (8 mL). The mixture was stirred at 130° C. under nitrogen for 16 hr. The insoluble solid was removed by filtration through silica gel/Celite pad (eluted with EtOAc). Silica-gel was added to the filtrate 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 (563 mg) as an off-white amorphous solid.
