Versuchsvorschrift

0.22 ml of 2 M aqueous sodium carbonate solution and 6.1 mg (0.007 mmol) of PdCl2(dppf) are added to a mixture of 60 mg (0.15 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 8A) and 22.7 mg (0.15 mmol) of 2-methoxyphenylboronic acid in 1 ml of DMF. The reaction mixture is heated at 80° C. for 14 h, then filtered through kieselguhr and evaporated to dryness. Purification of the crude product by preparative HPLC, subsequent addition of 1N hydrochloric acid and drying under high vacuum result in 12.8 mg (18% of theory) of the title compound.
