An amount of 14 g (42 mmol) of 9-bromo-10-phenylanthracene was dissolved in dehydrated THF and cooled to −80° C. Then, 31.2 ml (49 mmol) of a solution of n-butyllithium in n-hexane was added dropwise. Forty minutes later, 13 g (89 mmol) of triethyl borate was added. After two-hour reaction, a diluted hydrochloric acid solution was added and allowed to stand for 12 hours. Then, the separated organic layer was recrystallized to obtain 10 g (33.6 mmol) of 10-phenylanthracene-9-boronic acid. The yield was 75.2%.
