Versuchsvorschrift

To a microwave vial containing 6-(3,5-dimethylisoxazol-4-yl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-benzo[d]imidazol-2(3H)-one (100 mg, 0.28 mmol, 1 equiv.) was added 5-bromo-1-methyl-1H-pyrazole-4-carbonitrile (130 mg, 0.30 mmol, 2.5 equiv.), Pd(dppf)Cl2.CH2Cl2 (23 mg, 0.03 mmol, 0.1 equiv.) and DBU (253 μL, 1.69 mmol, 6 equiv.) and dissolved in DMSO-H2O (4 mL, 0.2 M, 2/1, v/v). The mixture was heated to 120° C. for 30 min in microwave. The reaction was concentrated in vacuo and purification was then carried out by reverse phase HPLC.
