Procedure

A solution of 200 mg (0.56 mmol) 5-chloromethyl-4-cyclopropyl-6-methoxymethyl-2-(4-trifluoromethyl-phenyl)-pyrimidine (example 113H]), 134 mg (0.56 mmol) 2-(4-hydroxy-2-methyl-phenoxy)-2-methyl-propionic acid ethyl ester (described in WO 02/092590) and 237 mg (0.73 mmol) cesium carbonate in 3 ml DMF was stirred for 3 h at RT. The reaction mixture was taken up in ether and washed with 1N HCl and water. After purification of the crude product by chromatography over silica gel with AcOEt/heptane 1:3, 257 mg of pure 2-{4-[4-cyclopropyl-6-methoxymethyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy-2-methyl-propionic acid ethyl ester could be isolated.
