After addition, the resulting solution was stirred for 2 hours. After a reaction, the reaction solution was washed with water, the solvent was removed, and the obtained product was purified by column chromatography to obtain a benzophenone derivative represented by the following formula (40) as 67.3 g (210.7 mmol, yield of 65%) of a yellow solid.
