Procedure

60.5 mg (1.51 mmol) of sodium hydride (60% suspension in mineral oil) are added to a solution, cooled to −20° C., of 250 mg (0.61 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-(2-methoxyphenyl)-1-benzofuran-2-carboxamide hydrochloride (Example 102) in 2.5 ml of DMF. After 30 min at room temperature and renewed cooling to −20° C., 33.9 μl (0.54 mmol) of iodomethane are added. After 18 h at room temperature, the reaction is stopped by adding water. The reaction mixture is purified by preparative HPLC. The product fractions are concentrated, codistilled with 1N hydrochloric acid, again concentrated and dried under high vacuum. 206 mg (79.7% of theory) of the title compound are obtained.
