실험 절차

0.67 ml of 2 M sodium carbonate solution and 18.3 mg (0.02 mmol) of PdCl2(dppf) are added to a mixture of 200 mg (0.45 mmol) of N-[(3S)-1-azabicyclo[2.2.2]oct-3-yl]-7-bromo-1-benzothiophene-2-carboxamide hydrochloride (Example 22A) and 80.2 mg (0.45 mmol) of 3-(acetamido)phenylboronic acid in 2 ml of DMF. The reaction mixture is heated at 80° C. for 17 h. A further 40.1 mg (0.22 mmol) of 3-(acetamido)phenylboronic acid, 1.34 ml of 1N sodium hydroxide solution and 73.2 mg (0.09 mmol) of PdCl2(dppf) are added, and the mixture is heated at 70° C. for a further 18 h. Cooling is followed by filtration through kieselguhr and purification by preparative HPLC. The product fractions are concentrated, taken up in a 5:1 mixture of methanol and 1N hydrochloric acid and again concentrated. Drying under high vacuum results in 124.5 mg (59% of theory) of the title compound.
