4-Chloro-5-(4-fluorophenyl)-6-[4-(methylsulfonyl)phenyl]-2-(trifluoro methyl)pyrimidine (0.5 g, 1.63 mmol), methyl vanillate (0.423 g, 2.33 mmol), potassium carbonate (0.24 g, 1.74 mmol) and acetonitrile (7 ml) were stirred at room temperature for 2 hours and subsequently the reaction mixture was refluxed for 6 hours. Further, potassium carbonate (0.08 g, 0.58 mmol) and vanillic ester (0.12 g, 0.66 mmol) were added to the reaction mixture and the refluxing was continued for another 4 hours. Subsequently the reaction mixture was poured onto ice-cold water, extracted with ethyl acetate (25 mL) and washed with brine solution. Evaporation of the organic layer yielded the required product. 1H-NMR (DMSO-d6) δ: 3.24 (s, 3H), 3.81 (s, 3H), 3.88 (s, 3H), 7.26-7.30 (m, 2H), 7.44 (d, 1H), 7.49-7.53 (m, 2H), 7.61-7.69 (m, 4H), 7.91 (d, 2H); MS m/z: 576.8 (M++1).
