Procedure

For example, when 2-(4-methoxyphenyl)-3-methyl-1,6-diphenyl-4(1H)-pyridinone is either dissolved or suspended in a suitable solvent, e.g., methylene chloride, benzene or chloroform, and a Lewis acid such as boron tribromide, boron trichloride or the like is then added to the resulting solution to conduct a reaction, 2-(4-hydroxyphenyl)-3-methyl-1,6-diphenyl-4(1H)-pyridinone is produced.
