Procedure
900.0 mg (3.50 mmol) of 6-bromo-1-benzothiophene-2-carboxylic acid (Example 10A), 697.0 mg (3.50 mmol) of (R)-3-aminoquinuclidine dihydrochloride, 1597.1 mg (4.20 mmol) of HATU, 1628.7 mg (12.60 mmol) of N,N-diisopropylethylamine and 8.0 ml of DMF are reacted by general method C. The reaction mixture is purified by preparative HPLC. The product is dissolved in a 1:1 mixture of 4 M hydrogen chloride in dioxane and 1N hydrochloric acid, and the solution is then concentrated. Recrystallization from methanol/ethanol (1:10) affords 594 mg (42% of theory) of the title compound in the form of yellowish-brown crystals.
