実験手順

0.28 g (1.0 mmol) rac-2-ethoxy-3-(2-methyl-1H-indol-5-yl)-propionic acid ethyl ester (preparation 5) were reacted with 0.23 g (1.1 mmol) 4-chloromethyl-2-phenyl-thiazole in 5 ml N,N-dimethylformamide in the presence of 0.09 g (2.0 mmol) sodium hydride (55%) in mineral oil) at room temperature for 16 hours. The reaction mixture was then diluted with water and extracted with dichloromethane. The combined organic phases were dried over MgSO4 and evaporated. The residue formed was purified by flash-chromatography (silica gel; eluent: gradient of n-heptane and ethyl acetate) to give 0.38 g (90%) of rac-2-ethoxy-3-[2-methyl-1-(2-phenyl-thiazol-4-ylmethyl)-1H-indol-5-yl]-propionic acid as light brown solid.
