実験手順
A solution of 2-[4-(bromomethyl)-3-fluorophenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (300 mg, 0.95 mmol), pyrrolidin-3-ol (99 mg, 1.1 mmol), and potassium carbonate (160 mg, 1.1 mmol) in acetonitrile (5 mL) was heated to 50° C. for 3 h. The reaction mixture was cooled, filtered and the filtrate was concentrated to afford the desired product (280 mg, 92%) as a red oil: ESI MS m/z 322 [C17H25BFNO3+H]+.
