実験手順

A mixture of 40 mg (0.29 mmol) of 4-(trifluoromethoxy)phenylboronic acid, 70 mg (0.19 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-5-fluoro-7-bromo-1-benzofuran-2-carboxamide (Example 5A), 0.57 ml (0.57 mmol) of 1N sodium hydroxide solution, 14 mg (0.02 mmol) of 1,1′-bis(diphenylphosphino)ferrocenepalladium(II) chloride and 2 ml of DMF is heated at 85° C. overnight. The solvent is removed under reduced pressure. The crude product is mixed with 1N sodium hydroxide solution and extracted three times with a total of 100 ml of ethyl acetate. The combined organic phases are dried over magnesium sulphate, and the solvent is removed under reduced pressure. The crude product is taken up in methanol and shaken together with acidic ion exchanger (Dowex® WX2-200) for about 20 min. The loaded ion exchanger is washed three times with 30 ml of methanol each time, then with water, again with methanol, with dichloromethane, again with methanol, with THF and finally once more with methanol. The product is eluted with methanol/triethylamine 95:5. The solvent is removed in a rotary evaporator under reduced pressure. Silica gel 60 (Merck, Darmstadt; eluent: dichloromethane/triethylamine 100:1, then dichloromethane/methanol/triethylamine 100:1:1 to dichloromethane/methanol/triethylamine 100:10:1) is used for final purification. The solvent is removed under reduced pressure. Finally, the last residues of solvent are removed under high vacuum. 52 mg (61% of theory) of the title compound are isolated.
