Under an argon atmosphere 5.0 mg (0.02 mmol) palladium(II)acetate and 14 mg (20 μmol) BINAP were added to 69 mg (0.25 mmol) 7-methoxy-3-piperidin-4-yl-1,3,4,5-tetrahydro-1,3-benzodiazepin-2-one, 84 mg (0.25 mmol) 3-bromo-5-(5-fluoroindoline-1-carbonyl)-pyridine-1-oxide and 0.12 g (0.38 mmol) caesium carbonate in 4.0 mL dioxane and the mixture was stirred overnight at 120° C. The reaction mixture was then evaporated down and the residue was dissolved in DMF/MeOH and purified by preparative HPLC-MS. The product-containing fractions were combined, the organic solvent was evaporated down and the residue was made alkaline with a 1N aqueous sodium hydroxide solution. The precipitate formed was suction filtered, washed with water and dried under HV.
