Reaction Steps
0.15 ml of 2 M aqueous sodium carbonate solution and 4.1 mg (0.005 mmol) of PdCl2(dppf) are added to a mixture of 40 mg (0.10 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-5-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 14A) and 12.1 mg (0.10 mmol) of phenylboronic acid in 1 ml of DMF. The reaction mixture is heated at 80° C. for 14 h, 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 7.3 mg (18% of theory) of the title compound.
