Versuchsvorschrift

To a solution of 8-bromo-4-(1-methyl-piperidin-4-yloxy)-2-phenyl-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulene (example 231) (150 mg) in toluene/dioxane/water 10/1/1 (6 mL) in a screw-capped vial are added benzylboronic pinacol ester (151 mg), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (50 mg) and potassium carbonate (137 mg). The vial is evacuated and filled with argon. The reaction mixture is stirred at 95° C. for 20 hours. Water is added to the reaction mixture, and the aqueous phase is extracted three times with dichloromethane. Pooled organic extracts are dried over magnesium sulphate, filtered and the solvent is removed under reduced pressure. The residue is purified by preparative HPLC-MS (Waters AutoPurification HPLC/MS System, Sunfire Prep C18 5 μm OBD 30×150 mm column, eluents: water/0.1% formic acid (A) and acetonitrile/0.1% formic acid (B), focus gradient from 23% (B) to 33% (B) in 10 minutes) to afford 8-benzyl-4-(1-methylpiperidin-4-yloxy)-2-phenyl-9,10-dihydro-4H-3,10a-diaza-benzo[f]azulene melting at 66° C.
