Procedure
54.1 Using general method A, with THF instead of DMF as solvent, [2-(4-chloro-benzoylamino)-thiazol-4-yl]-acetic acid ethyl ester (example 1.1) was coupled with tert-butyl-1-piperazine carboxylate to give 4-{2-[2-(4-chloro-benzoylamino)-thiazol-4-yl]-acetyl}-piperazine-1-carboxylic acid tert-butyl ester. White solid. MS 465.1 ([M+H]+)
