Reaktionsschritte
133.7 mg (0.52 mmol) of 5-bromo-1-benzothiophene-2-carboxylic acid, 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 according to the general procedure (variant A). The reaction mixture is purified by preparative HPLC. The product is dissolved in acetonitrile, and an excess of 1N hydrochloric acid is added. The solvent is then removed. 175 mg (84% of theory) of the title compound are isolated.
