In a 50 mL-volume flask, 12.2 g of phenyl glyoxylic acid was placed, and then 9.26 g of dichloromethyl methyl ether was dropwise added at room temperature. The mixture was stirred at room temperature for 1 hour. The reaction mixture was placed under reduced pressure (62° C./2 torr) to give 13.4 g of phenylglyoxylic acid chloride. The obtained phenylglyoxylic acid chloride was dropwise added to a mixture of 7.86 g of phenol, 7.26 g of pyridine and 10 mL of toluene. The resulting mixture was stirred at 50° C. for 2 hours.
