Reaction Steps

2-[4-(Bromomethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaboronate (5.00 g, 16.84 mmol), 3-methylimidazolidine-2,4-dione (2.11 g, 18.52 mmol, 1.1 equiv) and potassium carbonate (4.65 g, 33.7 mmol, 2 equiv) were combined and treated with N,N-dimethylformamide (17 mL). The mixture heated for 3 hours at 45° C., cooled to ambient temperature, diluted with ethyl acetate and washed with water (3×) and brine. The organic extracts were dried with sodium sulfate, filtered and concentrated in vacuo to afford the titled compound.
