Reaction Steps

Potassium vinyltrifluoroborate (356 mg, 242 μmol), ethyldiisopropylamine (48 μL, 279 μmol) and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium dichloromethane adduct (15.1 mg, 18.6 μmol) were added to a solution of 3-(4-bromo-3-methyl-phenyl)-imidazolidine-2,4-dione (50 mg, 186 μmol) in n-PrOH (372 μL) at room temperature in an N2 atmosphere. The mixture was stirred at 100° C. for 1.5 hours, and the reaction solution was then cooled. The reaction solution was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (dichloromethane-methanol) to give 3-(3-methyl-4-vinyl-phenyl)-imidazolidine-2,4-dione as a yellow brown form (33 mg, 82%).
