Versuchsvorschrift

(10,11-Dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl)-[3-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanone of Example 2 Step B (6.75 g, 15.8 mmol), 3-oxo-2-methylcyclohexen-1-yl trifluoromethanesulfonate (4.49 g, 17.4 mmol) and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II) dichloromethane adduct (0.387 g, 0.474 mmol) were combined in dimethylsulfoxide (79 mL). Aqueous sodium carbonate (2M, 39.5 mL, 79.0 mmol) was added and the reaction heated to 60° C. for 3 hours. After cooling to room temperature, the reaction mixture was diluted with water and washed with ethyl acetate. The combined extracts were washed with water and brine. The organic phase was dried over anhydrous sodium sulfate, filtered through silica gel and concentrated. The residue was purified by flash column chromatography on silica gel eluting with 50% ethyl acetate in hexane to provide 3.55 g of the title compound as a pale orange foam.
