Procedure

120 mg (0.30 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-6-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 11A), 10.5 mg (0.01 mmol) of PdCl2(PPh3)2 and 4.6 mg (0.02 mmol) of copper(I) iodide are dissolved in 1.5 ml of triethylamine/DMF (2:1) under argon and stirred at 60° C. for 1 h. Addition of 25.1 mg (0.45 mmol) of propargyl alcohol is followed by heating at 70° C. for a further 16 h. Cooling is followed by filtration through kieselguhr and purification by preparative HPLC, concentration and drying of the product under high vacuum. 12 mg (11% of theory) of the title compound are obtained.
