Procedure

534.2 mg (1.87 mmol) of tert-butyl 2-bromobenzylcarbamate, 474.1 mg (1.87 mmol) of bis(pinacolato)diboron, 397.0 mg (4.04 mmol) of potassium acetate, 45.5 mg (0.06 mmol) of PdCl2(dppf), 500 mg (1.24 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 8A), 3.11 ml of 2 M sodium carbonate solution and a further 45.5 mg (0.06 mmol) of PdCl2(dppf) in 6.0 ml of DMF are reacted by general method D. Purification by preparative HPLC is followed by concentration of the combined product fractions, taking up in methanol, addition of 1N hydrochloric acid, and stirring at room temperature for 30 min. Concentration and drying under high vacuum result in 121 mg (20% of theory) of the title compound.
