Reaktionsschritte

To a solution of 300 mg (0.91 mmol) 5-chloromethyl-4-(2-methoxy-ethyl)-2-(4-trifluoromethyl-phenyl)-pyrimidine and 199 mg (0.91 mmol) (5-hydroxy-indol-1-yl)-acetic acid ethyl ester in 5 ml DMF was added 443 mg (136 mmol) cesium carbonate. The reaction mixture was stirred at RT for 3 h and then taken up in ether, washed with 1N HCl and water. The crude product was purified by chromatography with AcOEt/heptane 1:4 to provide 152 mg of pure {5-[4-(2-methoxy-ethyl)-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-indol-1-yl}-acetic acid ethyl ester.
