1H-1,2,4-Triazole → HCID 13655350, compound

Participants

Reaction Steps

To a stirred mixture of 14 parts of 1H-1,2,4-triazole and 225 parts of N,N-dimethylformamide are added 6.2 parts of a sodium hydride dispersion 78%. When foaming has ceased, there are added 19.5 parts of 2-(2,4-dichlorophenyl)propyl methanesulfonate and stirring is continued for 6 hours at reflux. The reaction mixture is cooled, poured onto water and the product is extracted twice with 2,2'-oxybispropane. The combined extracts are washed with water, dried, filtered and evaporated. The residue is crystallized from petroleumether. The product is filtered off and dried, yielding 10.2 parts (58%) of 1-[2-(2,4-dichlorophenyl)propyl]-1H-1,2,4-triazole; mp. 79.5° C.
