Procedure
2-Phenyl-ethenesulfonic acid [6-(2-hydroxy-ethoxy)-5-p-tolyl-pyrimidin-4-yl]-amide (150 mg) was dissolved in THF (10 ml) and sodium hydride (45 mg; 55-65% in mineral oil) was added. The mixture was stirred for 15 min at rt., followed by the addition of DMF (2 ml) and 2-chloro-5-trifluoromethyl-pyridine (146 mg) and heating to 75° C. for 5 h. Then the reaction mixture was evaporated to dryness and water (15 ml) and citric acid was added. The precipitated product was filtered off, washed with water and dried. 2-Phenyl-ethenesulfonic acid {5-p-tolyl-6-[2-(5-trifluoromethyl-pyridin-2-yloxy)-ethoxy]-pyrimidin-4-yl}-amide (130 mg) could be obtained as a white powder. tR=5.92 (LC); [M+H]+=557.38 (ES+).
