实验过程

The title compound was prepared from N-[Nα-(9-fluorenylmethoxycarbonyl)-Nδ-trityl-L-glutaminyl]-2,5-dimethoxyaniline (988 mg, 1.33 mmol, example 82, step A) as described for example 82 (step B) using pyrrole-2-carboxylic acid (222 mg, 2.0 mmol) instead of caffeic acid. The crude material was purified by flash chromatography using successively 10%, 15% and 20% EtOAc/CH2Cl2. The title compound was obtained as white crystals (497 mg, 61%).
