Procedure

60 mg (0.15 mmol) of 7-(2-aminophenyl)-N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-1-benzofuran-2-carboxamide (Example 132), 26 mg (0.22 mmol) of cyclobutanecarbonyl chloride and 0.06 ml (0.44 mmol) of triethylamine are shaken in 2 ml of THF/DMF (1:1) at RT overnight. The solvent is removed under reduced pressure. Purification takes place by preparative HPLC. The product is dissolved in methanol, and an excess of 1N hydrochloric acid is added. The solvent is removed under reduced pressure. Drying under high vacuum results in 39 mg (56% of theory) of the title compound.
