Reaction Steps
180 mg (0.551 mmol) of [rac]-5-(1-chloro-ethyl)-4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidine (example 28H), 116 mg (0.551 mmol) of (4-hydroxy-2-methyl-phenoxy)-acetic acid ethyl ester (WO02092590) and 31 mg (0.71 mmol) sodium hydride (55% in oil) were stirred in 3 ml DMF over night. The reaction mixture was partitioned between ether and water. The crude product was purified by chromatography over silica gel with AcOEt/heptane 1:4 to give 157 mg of pure [rac]-(4-{1-[4-cyclopropyl-2-(4-trifluoromethyl-phenyl)-pyrimidin-5-yl]-ethoxy}-2-methyl-phenoxy)-acetic acid ethyl ester.
