Participants

Reaction Steps

To a solution of 4. g. of 1-methyl-3-(3-chlorophenyl)-5-(2-bromomethylphenyl)-1,2,4-triazole in 50 ml. of anhydrous benzene, 8.8 ml. of a benzene solution containing 20% of dimethylamine are added maintaining the temperature of about 5°-10° C. The mixture was maintained under stirring for 16 hours and then washed with 10% sodium hydroxide and with an aqueous solution of sodium chloride. The organic solution is dried over sodium sulfate and then evaporated. The crude product is purified by distillation at 175° C./0.07 mm Hg. Yield 86%.
