Reaction Steps
5-Bromo-2-isobutoxybenzonitrile and triisopropyl borate were dissolved in a mixed solvent of THF and toluene and an n-butyllithium-hexane solution was added dropwise to the solution at a temperature below −60° C. After the temperature was elevated to −20° C., 1M hydrochloric acid was added, followed by stirring at room temperature to obtain (3-cyano-4-isobutoxyphenyl)boronic acid. F: 220.
