Vorschrift

(S)-1-carbomethoxymethyl-3-(5-chloroindole-2-carbonylamino)-3,4-dihydrocarbostyril (Example 8) (5 mg) was dissolved in a mixture of tetrahydrofuran (1 mL) and 2 M ammonia in methanol solution (2 mL). After stirring for 16 h at room temperature, the solvent was evaporated and the residue was coevaporated with methanol (3 mL twice) under vacuum. Purification by reverse phase preparative HPLC provided the title compound (2.2 mg). HPLC/MS [M+H]+, 397.
