Reaktionsschritte
Prepared by the same method as described in example 3 except that (i) 2-chloro-4-iodo-aniline was used in place of 4-bromo-2-chloro-aniline in step 1, and (ii) (R)-tert-butoxycarbonylamino-[4-((R)-2-hydroxy-propoxy)-phenyl]-acetic acid was used in place of (R)-tert-butoxycarbonylamino-[4-(2-tert-butoxy-ethoxy)-phenyl]-acetic acid in step 2. (R)-tert-Butoxycarbonylamino-[4-((R)-2-hydroxy-propoxy)-phenyl]-acetic acid was prepared as described in example 48 except that (R)-2-methyl-oxirane was used in place of 2-(2bromo-ethoxy)-tetrahydropyran.
