HCID 54298340{2-[5-diisobutylcarbamoyl-2-(3,5-dimethylphenyl)-1H-indol-3-yl]-ethyl}carbamic acid tert-butyl ester

Versuchsvorschrift

To a solution of 3-(2-tert-butoxycarbonylaminoethyl)-2-(3,5-dimethylphenyl)-1H-indole-5-carboxylic acid (200 mg in 12 mL methylene chloride) was added 104 mg 1-hydroxybenzotriazole followed by 118 mg 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and the mixture stirred at room temperature. After 30 minutes, 0.35 mL of diisobutylamine was added and the mixture stirred at room temperature for 14 hours. The reaction was then concentrated in vacuo and purified by flash chromatography on silica gel (hexane:ethyl acetate, 2:1) to give the title compound (230 mg).
