Procedure

73 mg (0.20 mmol) of 7-(3-aminophenyl)-N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-1-benzofuran-2-carboxamide (Example 114), 69 mg (0.61 mmol) of methanesulphonyl chloride and 0.14 ml (1.01 mmol) of triethylamine are heated in 3 ml of THF/DMF (1:1) at 50° C. overnight. Cooling is followed by addition of water, filtration and removal of the solvent 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 16 mg (14% of theory) of the title compound.
