PROCEDURE

实验过程

The title compound was prepared from N-[Nα-(9-fluorenylmethoxycarbonyl)-Nδ-methyltrityl-L-glutaminyl]-3,4-dihydroxybenzylamine (900 mg, 1.2 mmol, example 26, step A) as described for example 26 (step B) using caffeic acid (326 mg, 1.8 mmol) instead of 4-hydroxy-3-nitrobenzoic acid. The crude material was purified by flash chromatography using a solvent gradient from 30% to 70% EtOAc/CH2Cl2/1% AcOH. The title compound was obtained as a yellow powder (430 mg, 52%).
