m-Chloroperbenzoic acid → HCID 178477615, compound

Participants

Reaction Steps

5 g (0.0155 mol) of 1-(4-chlorophenyl)-1-[1-(ethylthio)-1-cyclopropyl]-2-(1,2,4-triazol-yl)-1-ethanol (see Example 1) are stirred with 3.3 g of m-chloroperbenzoic acid (80-90% strength) in 40 ml of methylene chloride overnight at room temperature and then for one hour under reflux. Thereafter, the mixture is washed with twice 20 ml of 5% strength aqueous sodium hydroxide solution and twice with water. The organic phase is dried over sodium sulphate and evaporated down in vacuo. The residue is recrystallized from glycol monomethyl ether acetate. 3 g (57% of theory) of 1-(4-chlorophenyl)-1-[1-(ethylsulphinyl)-1-cyclopropyl]-2-(1,2,4-triazol-yl)-1-ethanol of boiling point 185° C. are obtained.
