Procedure
A solution of 367 mg (1.11 mmol) 4-butyl-5-chloromethyl-2-(4-trifluoromethyl-phenyl)-pyrimidine (example 115C]) and 250 mg (1.11 mmol) 2-(4-hydroxy-phenoxy)-2-methyl-propionic acid ethyl ester [Newman, Melvin S.; Cella, James A. Monoalkylation of hydroquinone. Journal of Organic Chemistry (1974), 39(2), p 214–15] in 4 ml DMF was treated with 436 mg (1.34 mmol) cesium carbonate. The reaction mixture was stirred for 24 h at RT and then it was taken up in ether and washed with 1N HCl and water. The crude product was purified by chromatography over silica gel with AcOEt/heptane 1:4 to provide 344 mg pure 2-{4-[4-butyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-phenoxy}-2-methyl-propionic acid ethyl ester.
