Reaktionsschritte
4-Phenoxymethylphenylmethanol 4 (0.857 g, 4.0 mmol), (R)-2-isocyanato-3-phenyl-propionic acid methyl ester 5 (1.026 g, 5.0 mmol) and 4-dimethylaminopyridine (DMAP) (10 mg) were combined, heated until molten, and stirred for 20 min. Upon cooling, the residue was purified by chromatography to give about 1.6 g of (R)-2-(4-phenoxymethyl-benzyloxycarbonylamino)-3-phenyl-propionic acid methyl ester 6.
