Reaction Steps

903.8 mg (3.52 mmol) of 7-bromo-1-benzothiophene-2-carboxylic acid, 700.0 mg (3.52 mmol) of R-aminoquinulidine dihydrochloride; 1604.0 mg (4.22 mind) of HATU, 1635.7 mg (12.66 mmol) of N,N-diisopropylethylamine and 7.0 ml of DMF are reacted by general method B. The reaction mixture is purified by preparative HPLC. The product is dissolved in a 1:1 mixture of 4 M HCl in dioxane and 1 N hydrochloric acid and then concentrated and dried under high vacuum. 1087 mg (77% of theory) of the title compound are obtained.
