Procedure

A mixture of 180 mg (0.86 mmol) of 4-(4-morpholinyl)phenylboronic acid, 200 mg (0.57 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-6-bromo-1-benzofuran-2-carboxamide (Example 2A), 1.72 ml (1.72 mmol) of 1N sodium hydroxide solution, 40 mg (0.06 mmol) of 1,1′-bis(diphenylphosphino)ferrocenepalladium(II) chloride and 2 ml of DMF is heated at 80-85° C. for 18 h. The solvent is removed under reduced pressure. The crude product is purified on silica gel 60 (Merck, Darmstadt; eluent: dichloromethane, dichloromethane/methanol 20:1, dichloromethane/methanol/ammonia 80:20:2). The solvent is removed under reduced pressure. Finally, the last residues of solvent are removed under high vacuum. 79 mg (32% of theory) of the title compound are isolated.
