실험 절차

0.28 g (1.0 mmol) rac-2-ethoxy-3-(3-methyl-1H-indol-5-yl)-propionic acid ethyl ester (preparation 4) and 0.30 g (1.2 mmol) 4-chloromethyl-2-(4-isopropyl-phenyl)-5-methyl-oxazole were dissolved under argon in 5.0 ml N,N-dimethylformamide; 0.048 g (1.1 mmol) sodium hydride (55% in mineral oil) were added and the reaction mixture then stirred for 48 hours at ambient temperature. It was then diluted with water and extracted with ether. The combined organic phases were dried over MgSO4 and evaporated. The residue formed was purified by flash-chromatography (silica gel; eluent: gradient of hexane and ethyl acetate) to give 0.32 g (67%) of rac-2-ethoxy-3-{1-[2-(4-isopropyl-phenyl)-5-methyl-oxazol-4-ylmethyl]-3-methyl-1H-indol-5-yl}-propionic acid ethyl ester as colorless oil.
