1H-1,2,4-Triazole → HCID 13295576, compound

Participants

Reaction Steps

9.4 g (0.04 mole) of 2-chloromethyl-2-(4-chlorophenoxymethyl)-oxirane are added dropwise to a mixture of 13.6 g (0.2 mole) of 1,2,4-triazole and 13.8 g (0.1 mole) of potassium carbonate in 200 ml of acetone, while stirring. The reaction mixture is stirred at room temperature for 15 hours and then under reflux for 22 hours. It is then filtered cold and the filtrate is concentrated in vacuo. The oily residue is dissolved in chloroform and the solution is washed with water, dried over sodium sulphate and purified by chromatography (silica gel 60 Merck, chloroform/methanol=20/1). 5.8 g (43% of theory) of 2-(4-chlorophenoxymethyl)-1,3-di(1,2,4-triazol-1-yl)-2-hydroxypropane of melting point 99° C. (Example 1) and 2.0 g (15% of theory) of 2-(4-chlorophenoxymethyl)-2-hydroxy-1-(1,2,4-triazol-1-yl)-3-(1,2,4-triazol-4-yl)-propane (Example 2) of melting point 160° C. are obtained.
