YieldReaction ConditionsOperation in experiment
98.8% With dihydrogen peroxide; sodium sulfite In methanol; water EXAMPLE 2
186.4 g of fenbendazole are dissolved in 700 ml of methanol, 513 g of 48percent strength hydrobromic acid and 400 ml of water at 60° C., and 65.4 g of a 35percent strength hydrogen peroxide solution are added at a pH of -0.5.
The reaction solution is heated at 60° C. for 7 hours, and 10.0 g of sodium sulfite are then added.
After cooling to room temperature, the reaction mixture is introduced into 20percent strength sodium hydroxide solution, the product crystallizing out.
After drying in vacuo, 194.5 g of oxfendazole remain, corresponding to a yield of 98.8percent, relative to the fenbendazole employed.
The purity is 98.7percent.
