실험 절차

5.20 g (21.57 mmol) of 7-bromobenzofuran-2-carboxylic acid (Example 29A), 4.3 g (21.57 mmol) of (R)-3-aminoquinuclidine dihydrochloride, 9.84 g (25.89 mmol) of HATU, 13.53 ml (74.68 mmol) of N,N-diisopropylethylamine and 21 ml of DMF are reacted by general method C. The solvent is removed under reduced pressure, and the crude product is taken up in 100 ml of ethyl acetate and washed 15 times with a total of 1.5 1 of 1N sodium hydroxide solution. The organic phase is dried over magnesium sulphate and freed of solvent. 5.2 g (69% of theory) of the title compound are isolated.
