1H-1,2,4-Triazole → Tebuconazole

참여 물질

반응 단계

A solution of 17.9 g (0.075 mole) of 2-(4-chlorophenylethyl)-2-tert.-butyloxirane and 6.9 g (0.1 mole) of 1,2,4-triazole in 30 ml of ethanol in a sealed tube is heated at 150° C. for 20 hours. The tube is allowed to cool and the reaction solution is evaporated. The residue is dissolved in ether, washed three times with water and once with sodium chloride solution, dried over sodium sulphate and evaporated. The residue is chromatographed over a column of silican gel (mobile phase: dichloroethane/ethyl acetate 1:1). 12.3 g (53.2% of theory) of 1-(4-chlorophenyl)-4,4-dimethyl-3-(1,2,4-triazol-1-yl-methyl)-3-pentanol are obtained as a viscous oil.
