Versuchsvorschrift

To a solution of 3-{2-[tert-butoxycarbonyl-(4-pyridin-4-yl-butyl)amino]ethyl}-2-(3,5-dimethylphenyl)-1H-indole-5-carboxylic acid (1.44 g in 25 mL N,N-dimethylformamide) at 0° C. was added 540 mg of 1-hydroxybenzotriazole (HOBt) followed by 0.44 mL 4-methylnorpholine and 365 mg N,O-dimethylhydroxylamine hydrochloride. After 15 minutes, 815 mg 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) was added and the mixture allowed to warm to room temperature. After 3 days reaction time, an additional portion of 540 mg of HOBt, 0.44 mL 4-methylmorpholine, 365 mg N,O-dimethylhydroxylamine hydrochloride and 815 mg EDC were added. The reaction stopped after 4 days by concentration in vacuo and reconcentration from toluene to remove all volatiles. The residue was solvated in ethyl acetate and washed sequentially with saturated aqueous sodium bicarbonate and brine, then dried over sodium sulfate. Purification of the concentrate by flash chromatography on silica gel (hexane:ethyl acetate, 30:70; then 20:80; then 0:100) gave the title compound (1.4 g).
