Prepared by the same method as described in example 1 except that (i) chlorination of the 5-position of the imidazole ring with N-chlorosuccinimide in step F was omitted; (ii) (R)-tert-butoxycarbonylamino-[4-((S)-2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-phenyl]-acetic acid (prepared as described in example 33) was used in place of (R)-tert-butoxycarbonylamino-[4-(2-tert-butoxy-ethoxy)-phenyl]-acetic acid in step 36-G, and (iii) cyclization of (R)-2-amino-2-[4-((R)-2,3-dihydroxy-propoxy)-phenyl]-N-{(1S,2S)-1-[5-(2-fluoro-4-iodo-phenyl)-1H-imidazol-2-yl]-2-phenyl-propyl}-acetamide in step 36-H was performed as described in example 34.
