Procedure

288 μl (2.42 mmol) of benzyl bromide and 502 mg (3.63 mmol) of potassium carbonate are added to a solution of 500 mg (1.21 mmol) of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-(2-methoxyphenyl)-1-benzofuran-2-carboxamide hydrochloride (Example 102) in 12.5 ml of DMF. After 20 h at 50° C., the reaction mixture is purified by preparative HPLC. The product fractions are concentrated and, after addition of 50% strength hydrobromic acid, again concentrated and dried under high vacuum. Recrystallization from cyclohexane/acetone affords 537 mg (77% of theory) of the title compound.
