PROCEDURE

实验过程

The title compound was prepared from N-[Nα-(9-fluorenylmethoxycarbonyl)-Nδ-trityl-L-glutaminyl]-2,5-dimethoxyaniline (703 mg, 0.94 mmol, example 82, step A) as described for example 82 (step B) using 4,8-dihydroxyquinoline-2-carboxylic acid (291 mg, 1.42 mmol) instead of caffeic acid. The crude material was purified by flash chromatography using initially 20% then 50% EtOAc/CH2Cl2. The title compound was obtained as white crystals (150 mg, 22%).
