Procedure

Under an atmosphere of argon, 62 mg (0.14 mmol) of the compound from Example 31A and 40 mg (0.21 mmol) of 2-(trifluoromethyl)phenylboronic acid were dissolved in 2 ml of toluene. 6.5 mg (0.007 mmol) of tris(dibenzylideneacetone)dipalladium, 5.6 mg (0.014 mmol) of 2-dicyclohexylphosphino-2′-(N,N-dimethylamino)biphenyl and 60 mg (0.28 mmol) of potassium phosphate were then added, and under argon the mixture was heated to 110° C. for 48 h. For work-up, the mixture was diluted at RT with 10 ml of ethyl acetate and 10 ml of water, the organic phase was separated off and the aqueous phase was extracted two more times with in each case 10 ml of ethyl acetate. The combined organic phases were dried over sodium sulfate, filtered and concentrated under reduced pressure. The crude product was purified chromatographically [Method 19]. This gave 10 mg (13% of theory) of the target compound.
