Procedure

Add a 2.5 M solution of n-butyllithium in hexane (0.60 mL, 1.10 mmol) to a solution of 5-(3-bromophenyl)isoxazol-3-ol (120 mg, 0.50 mmol) and triisopropyl borate (113 mg, 0.60 mmol) in a mixture of toluene (2.5 mL) and THF (2.5 mL) at −78° C. After 1.5 h, warm the mixture to −20° C. and add a 2.0 N aqueous HCl solution (1 mL). Extract the mixture with EtOAc after warm to room temperature. Dry, filter and concentrate the organic layer to a white solid.
