Vorschrift

30 mg (0.08 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-5-amino-1-benzo-thiophene-2-carboxamide dihydrochloride are dissolved in 1 ml of DMF, and 33.5 μl (0.24 mmol) of triethylamine are added. At 0° C., 15.7 mg (0.12 mmol) of furan-2-carbonyl chloride are added. After 3 h of stirring at RT, the reaction mixture is separated by preparative HPLC. The product fraction is concentrated under reduced pressure and codistilled with 4M HCl in dioxane. 12 mg (34.7% of theory) of the title compound are obtained.
