    SonstigeThe crude product was recrystallized from ethyl acetate/Skellysolve B

Vorschrift

The title compound was prepared by the general method of Example 1 using 24.9 g (0.1 mole) of t-butoxycarbonyl-D-methionine (BOC-D-Met) and 13.8 g (0.11 mole) of glycine methyl ester hydrochloride. The crude product was recrystallized from ethyl acetate/Skellysolve B to give the title compound, which was used in subsequent reactions without further purification.
