Versuchsvorschrift

Alternatively, (R)-3-amino-1-carbomethoxymethyl-3,4-dihydrocarbostyril hydrochloride (19 mg) was added to a mixture of tetrahydrofuran (10 mL), 5-chloroindole-2-carboxylic acid (15 mg), 1-hydroxy-7-azabenzotriazole (12 mg), and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (16 mg) at room temperature. Diisopropylethylamine (19 mg) was added, and the resulting yellow suspension was stirred under argon for 16 h, during which a solution formed. The solution was diluted with ethyl acetate (50 mL) and washed sequentially with 1.0 M aqueous hydrochloric acid (25 mL twice), 1.0 M aqueous sodium hydroxide (20 mL) and brine (20 mL), dried over anhydrous sodium sulfate and evaporated under vacuum. One half of the residue was purified by reverse phase preparative HPLC to provide the title compound (7.6 mg).
