The title compound was prepared from N-[Nα-(9-fluorenylmethoxycarbonyl)-O-tert-butyl-L-seryl]dopamine (610 mg, 1.2 mmol, example 42, step A) as described for example 42 (step B) using 3,4-di-(4-fluorobenzyloxy)benzoic acid (653 mg, 1.8 mmol, step A of this example) instead of caffeic acid. The crude material was purified by flash chromatography using successively 15%, 35% and 50% EtOAc/CH2Cl2 as the eluent. The title compound was obtained as a yellow powder (207 mg, 27%).
