Reaction Steps

To a 100 ml Schlenk reaction vessel were added under a nitrogen atmosphere 755 mg (1.95=mol) of 1,2-dibromo-4,5-diphenylbenzene synthesized in 2) and 12 ml of THF. The solution was cooled to −100° C. and 1.3 ml (2.1 mmol) of a hexane solution of n-butyllithium (manufactured by Kanto Chemical Co., Ltd., 1.59M) was added dropwise. After 30 minutes of aging, 472 my (2.51 mmol) of triisopropyl borate (manufactured by Tokyo Chemical Industry Co., Ltd.) was added dropwise. After the temperature was gradually raised to room temperature, 3N hydrochloric acid was added and phase separation was conducted. The organic phase was concentrated under reduced pressure to obtain 770 my of a white solid (2-phenyl-5-bromo-4-biphenylboronic acid).
