実験手順

60 mg (0.15 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 8A) and 22.7 mg (0.15 mmol) of 4-(hydroxymethyl)phenylboronic acid are introduced into 1 ml of DMF. Addition of 0.22 ml of 2 M aqueous sodium carbonate solution and 6.1 mg (0.01 mmol) of PdCl2(dppf) is followed by heating to 80° C. After 14 h, the reaction mixture is filtered through kieselguhr and evaporated to dryness. The crude product is purified by preparative HPLC. The product is dissolved in methanol and an excess of 4N hydrogen chloride in dioxane is added. Drying under high vacuum results in 9 mg (9% of theory) of the title compound.
