Reaction Steps

4-Chloro-5-(1-chlorovinyl)-2-methyl-6-trifluoromethylpyrimidine (1.83 g) was dissolved in acetonitrile (20 ml) under stirring in room temperature. The mixture was added imidazole (1.45 g) and refluxed 3 hr and then cooled to room temperature and added water. The mixture was extracted with chloroform. The chloroform layer was washed with water and brine, respectively and dried over magnesium sulfate. The solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (chloroform-THF) to give 5-(1-chlorovinyl)-4-imidazol-1-yl-2-methyl-6-trifluoromethyl-pyrimidine (1.34 g) as pale brown oil. 1H-NMR (δ, ppm); 2.82 (s, 3H), 5.78 (d, 1H), 6.03 (d, 1H), 7.21 (br, 1H), 7.87 (br, 1H), 8.55 (br, 1H).
