実験手順

0.22 ml of 2 M aqueous sodium carbonate solution and 6.1 mg (0.007 mmol) of PdCl2(dppf) are added to a mixture of 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 30.9 mg (0.15 mmol) of 4-(4-morpholinyl)phenylboronic acid in 1 ml of DMF. The reaction mixture is heated to 80° C. After 4.5 h, a further 6.1 mg (0.007 mmol) of PdCl2(dppf) are added. After a further 12 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 20.6 mg (25% of theory) of the title compound.
