tert-butyl N-(pyrrolidin-3-yl)carbamate → {1-[2-(4-{2-[2-(4-Chloro-benzoylamino)-thiazol-4-yl]-acetyl}-piperazin-1-yl)-acetyl]-pyrrolidin-3-yl}-carbamic acid tert-butyl ester

Participants

Reaction Steps

In analogy to example 22.3, (4-{2-[2-(4-chloro-benzoylamino)-thiazol-4-yl]-acetyl}-piperazin-1-yl)-acetic acid (example 22.2) was coupled with 3-(tert-butyloxycarbonylamino)pyrrolidine, using general method C, to give {1-[2-(4-{2-[2-(4-chloro-benzoylamino)-thiazol-4-yl]-acetyl}-piperazin-1-yl)-acetyl]-pyrrolidin-3-yl}-carbamic acid tert-butyl ester. Off-white solid. MS 591.3 ([M+H]+)
