Procedure

254.2 mg (1.20 mmol) of 3-chloro-1-benzothiophene-2-carboxylic acid, 238 mg (1.20 mmol) of S-3-aminoquinuclidine dihydrochloride, 545.4 mg (1.43 mmol) of HATU, 556.1 mg (4.30 mmol) of N,N-diisopropylethylamine and 2.0 ml of DMF are reacted according to the general procedure (variant B). The reaction mixture is purified by preparative HPLC. The product is dissolved in 4M HCl in dioxane and then reconcentrated. 213 mg (49.9% of theory) of the title compound are obtained. The analytical data correspond to those of the racemate (example 14).
