実験手順

(S)-1-allyl-3-amino-3,4-dihydrocarbostyril hydrochloride (7.6 mg) was added to a mixture of tetrahydrofuran (4 mL), 5-chloroindole-2-carboxylic acid (6.9 mg), 1-hydroxy-7-azabenzotriazole (5.5 mg), and 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (7.7 mg) at room temperature. Diisopropylethylamine (12 mg) was added, and the resulting yellow suspension was stirred under argon for 16 h, during which a solution formed. The solution was evaporated under vacuum and the residue was directly purified by reverse phase preparative HPLC to provide the title compound (6.5 mg). HPLC/MS [M+H]+, 380; HPLC/MS [M+Na]+, 402.
