Procedure

151.1 mg (0.49 mmol) of 3-(4-morpholinyl)phenyl trifluoromethanesulphonate (Example 17A), 142.2 mg (0.56 mmol) of bis(pinacolato)diboron, 119.1 mg (1.21 mmol) of potassium acetate, 13.7 mg (0.02 mmol) of PdCl2(dppf), 144 mg (0.37 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzofuran-2-carboxamide hydrochloride (Example 30A), 0.93 ml of 2 M sodium carbonate solution and a further 13.7 mg (0.02 mmol) of PdCl2(dppf) in 2 ml of DMF are reacted by general method D. Drying under high vacuum results in 32 mg (18% of theory) of the title compound.
