Reaction Steps
To a stirred solution of (S)-2-[3-(2-tert-butoxycarbonylamino-1-methylethyl)-2-(3,5-dimethylphenyl)-1H-indol-5-yl]-2-methylpropionic acid in dry methylene chloride at 0° C. is added 1-hydroxybenzotriazole followed by 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and the reagents allowed to mix for 1 hour. At this time diethylamine is added followed by 1.5 mL triehtylamine and the reaction stirred at room temperature. After completion, the mixture is concentrated in vacuo and purified by flash chromatography on silica gel to give the title compound.
