Procedure

A mixture of 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (220 mg, 1.0 mmol), 2-chloro-N-methylacetamide (129 mg, 1.2 mmol), and K2CO3 (207 mg, 1.5 mmol) in DMF (1.5 mL) was stirred at 80° C. overnight. The mixture was poured into water and extracted with EtOAc. The combined extracts were dried over Na2SO4, filtered, and concentrated. The residue was purified by chromatography to give the title compound in the yield of 72%. MS (m/z): 292 (M+H)+.
