Procedure

200 mg (0.50 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 8A) and 68.2 mg (0.50 mmol) of 3-aminophenylboronic acid are introduced into 1.5 ml of DMF. Addition of 0.78 ml of 2 M sodium carbonate solution and 20.3 mg (0.02 mmol) of PdCl2(dppf) is followed by heating at 60° C. for 18 h. After cooling, the reaction mixture is filtered through kieselguhr and purified by separation by preparative HPLC. The product fractions are concentrated and, after addition of a 3:1 mixture of acetonitrile and 1N hydrochloric acid, again concentrated. Drying under high vacuum results in 201 mg (98% of theory) of the title compound.
