525 mg (1.48 mmol) tert-butyl[1-(4-bromo-phenyl)-5-oxo-pyrrolidin-3-yl]-carbamate are dissolved in 30 ml of toluene and 5 ml of water and combined with 318 mg (1.77 mmol) 2-(N,N-dimethylaminomethyl)phenylboronic acid, 48 mg (0.15 mmol) tetrabutylammonium bromide and 314 mg (2.96 mmol) potassium carbonate, and lastly 173 mg (0.15 mmol) tetrakis(triphenylphosphine)palladium(0) are added. The reaction solution is refluxed for 90 minutes at 400 Watt in the microwave. Then another 330 mg (1.84 mmol) 2-(N,N-dimethylaminomethyl)phenylboronic acid are added and the mixture is heated for one hour at 400 Watt in the microwave. The reaction solution is evaporated to dryness i. vac. The residue is purified by reversed phase chromatography.
