実験手順

Prepared by the same method as described in example 1 except that (i) steps A, B, and C were omitted; (ii) commercially available 1-(4-iodo-phenyl)-ethanone was used in place of 1-(2-fluoro-4-iodo-phenyl)-ethanone in step 18-D; (iii) (S)-2-tert-butoxycarbonylamino-3-phenyl-propionic acid was used in place of (2S,3S)-2-tert-butoxycarbonylamino-3-phenyl-butyric acid in step 18-E; (iv) chlorination of the 5-position of the imidazole ring with N-chlorosuccinimide in step 18-F was omitted; (v) (R)-2-tert-butoxycarbonylamino-pent-4-ynoic acid was used in place of (R)-tert-butoxycarbonylamino-[4-(2-tert-butoxy-ethoxy)-phenyl]-acetic acid in step 18-G; and (vi) in step 18-H, formic acid (neat) heated to 30° C. was used in place of trifluoroacetic acid and silylation with chlorotrimethylsilane and triethylamine was omitted. HR-MS: calcd for C23H19IN4O2 [M+H+] 511.0626. Found 511.0623.
