실험 절차

In analogy to the procedure described in example 3 c], (6-hydroxy-indol-1-yl)-acetic acid tert-butyl ester (example 6 b]) was reacted with [rac]-4-(tert-butyl-dimethyl-silanyloxy)-1-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-butan-1-ol in the presence of tributylphosphine and N,N,N′,N′-tetramethyl azodicarboxamide to obtain [rac]-(6-[4-(tert-butyl-dimethyl-silanyloxy)-1-[4-methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-butoxy}-indol-1-yl)-acetic acid tert-butyl ester as yellow oil.
