Mode opératoire

A mixture of a 6,6′-bis(2-methoxyphenyl)-2,2′-bipyridyl ligand (0.3 g) and pyridine hydrochloride (10 g) was heated for 4 hours at 160° C. under a nitrogen atmosphere. After cooling the reaction solution to a room temperature, chloroform (20 ml) and water (20 ml) were added to the reaction solution for separation. Thereafter, the organic layer was concentrated. Purification by silica gel chromatography (chloroform as a developing solvent) was carried out, to obtain 0.2 g of 6,6′-bis(2-hydroxyphenyl)-2,2′-bipyridyl.
