Versuchsvorschrift

Boc-Glu-OtBu (75 mg, 0.247 mmol), HATU (112 mg, 0.296 mmol) and HOAt (41 mg, 0.296 mmol) were dissolved in 1 mL of DMF. Triethylamine (52 μL) was added thereto and stirred at room temperature for 10 minutes. 3-Sulfoaniline (43 mg, 0.247 mmol) was added thereto and stirred overnight at room temperature. After removing a solvent, purification was conducted in accordance with the purification process A. The obtained intermediate was dissolved in 2 mL of a trifluoroacetic acid and stirred at room temperature for 3 hours, and a solvent was removed therefrom. The obtained product was purified in accordance with the purification process A to obtain a title compound.
