Procedure

tert-Butyl (E)-(2S,3S)-3-[(S)-2-(4-butoxy-phenyl)-1-methoxycarbonyl-ethylcarbamoyl]-11-heptylsulfanyl-2-hydroxy-2-(2-methoxy-ethyl)-undec-4-enoate (ESI (LC/MS positive mode) m/z 722 (M+H); Rt 3.13 min.) was synthesized by using methyl (S)-2-amino-3-(4-butoxy-phenyl)-propionate and conditions at 50° C., for 2.5 days instead of methyl (S)-2-amino-3-(4-but-2-ynyloxy-phenyl)-propionate and the conditions in Step C-6. Then, tert-butyl (E)-(2S,3S)-3-[(S)-2-(4-butoxy-phenyl)-1-methoxycarbonyl-ethylcarbamoyl]-11-(heptane-1-sulfonyl)-2-hydroxy-2-(2-methoxy-ethyl)-undec-4-enoate was first synthesized (ESI (LC/MS positive mode) m/z 754 (M+H); Rt 2.32 min) under conditions similar to those in Step C-7. Subsequently, (E)-(2S,3S)-3-[(S)-2-(4-butoxy-phenyl)-1-methoxycarbonyl-ethylcarbamoyl]-11-(heptane-1-sulfonyl)-2-hydroxy-2-(2-methoxy-ethyl)-undec-4-enoic acid (No. 5514406) was synthesized by the reaction under conditions similar to those in Step C-8.
