Procedure

133.7 mg (0.52 mmol) of 5-bromo-1-benzothiophene-2-carboxylic acid (Example 13A), 155.4 mg (0.78 mmol) of (R)-3-aminoquinuclidine dihydrochloride, 296.7 mg (0.78 mmol) of HATU, 369.8 mg (2.86 mmol) of N,N-diisopropylethylamine and 1.5 ml of DMF are reacted by general method C. The reaction mixture is purified by preparative HPLC. The product is dissolved in acetonitrile, and an excess of 1N hydrochloric acid is added. Finally, the solvent is removed. 175 mg (84% of theory) of the title compound are isolated.
