Reaction Steps
4-Cyano-5-iodo-2-methylthio-6-trifluoromethylpyrimidine (0.50 g) was dissolved in isopropanol (5 ml) and added water (10 ml), sodium azide (0.19 g) and zinc bromide (0.16 g) with stirring in room temperature. The mixture was refluxed for 3 hr and then cooled to room temperature and then added 3N-HCl to acidify. The mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with water and brine, respectively and dried over magnesium sulfate. The solvent was removed under reduced pressure to give 5-iodo-2-methylthio-4-(2H-tetrazol-5-yl)-6-trifluoromethyl-pyrimidine (0.5 g) as colorless crystalline solid, mp 196-200° C.
