Versuchsvorschrift

To a solution of 4-[10-chloro-7-(1-ethylpropyl)-2,3,4,5-tetrahydro-1H-[1,3]diazepino[1,2-a]benzimidazol-1-yl]-3-methylbenzoic acid (330 mg, 0.775 mmol) in N,N-dimethylformamide (4.0 mL) were added 1-hydroxy-1H-benzotriazole ammonium salt (172 mg, 1.01 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (163 mg, 0.853 mmol). The mixture was stirred at room temperature for 11 hr. The mixture was diluted with saturated aqueous sodium hydrogen carbonate, and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel eluting with a 80-100% ethyl acetate/n-hexane gradient mixture. The filtrate was concentrated in vacuo to give the solid, which was purified by preparative HPLC to give a mixture contained an intermediate of the title compound as the trifluoroacetic acid salt. The mixture was washed with aqueous sodium hydrogen carbonate and extracted with ethyl acetate. The extract was washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo to give the solid, which was recrystallized from ethanol/diisopropyl ether to give the title compound as a colorless crystal (58.5 mg, 0.138 mmol, 18%).
