Reaction Steps

0.58 ml of 2 M aqueous sodium carbonate solution and 15.9 mg (0.02 mmol) of PdCl2(dppf) are added to a mixture of 150 mg (0.39 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzofuran-2-carboxamide hydrochloride (Example 30A) and 66.1 mg (0.39 mmol) of 5-acetyl-2-thienylboronic acid in 2 ml of DMF. The reaction mixture is heated at 70° C. for 18 h and then filtered through kieselguhr and evaporated to dryness. Purification of the crude product by preparative HPLC, subsequent addition of a 1:1 mixture of methanol and 1N hydrochloric acid, concentration and drying under high vacuum result in 83.6 mg (49.9% of theory) of the title compound.
