Procedure

72 mg (0.15 mmol) of the compound from Example 101A and 59 mg (0.23 mmol) of 2-chloro-phenylboronic acid were dissolved in 2 ml of dioxane. A stream of argon was passed through this solution for 10 min, and 8.7 mg (0.008 mmol) of tetrakis(triphenylphosphine)palladium(0) were added under argon. The mixture was heated to the boil, and 0.15 ml (0.30 mmol) of a 2 N aqueous sodium carbonate solution was added under argon. The mixture was then stirred under reflux for 20 h. After cooling to RT, the mixture was diluted with 10 ml of water and extracted twice with in each case 15 ml of ethyl acetate. The combined organic phases were dried over magnesium sulfate, filtered and concentrated under reduced pressure. The crude product was purified chromatographically [Method 19]. This gave 51 mg (61% of theory) of the target compound.
