Participants

Reaction Steps

To a solution of 400 mg (1.22 mmol) 4-butyl-5-chloromethyl-2-(4-trifluoromethyl-phenyl)-pyrimidine (example 115C]) and 290 mg (1.22 mmol) 2-(4-hydroxy-2-methyl-phenoxy)-2-methyl-propionic acid ethyl ester (described in WO 02/092590) in 4 ml DMF was added 90 mg (2.06 mmol) of sodium hydride (55% in oil). The reaction mixture was stirred for 2 h at RT, 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 347 mg pure 2-{4-[4-butyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-ylmethoxy]-2-methyl-phenoxy}-2-methyl-propionic acid ethyl ester.
