Participants

Reaction Steps

To a solution of 5 g of 2-methyl-5-(4-methyl-1-piperazinyl)-11H-1,2,4-triazolo[2,3-c][1,3]benzodiazepine in 50 ml of methylene chloride is added in portions 3.75 g of m-chloroperbenzoic acid with stirring at 0°. The mixture is then stirred at room temperature overnight and evaporated to dryness. The foamy residue is passed through 100 g of Amberlite IRA-400 ion exchange resin using water as eluent. Evaporation of the eluent gives 2-methyl-5-(4-methyl-4-oxido-1-piperazinyl)-11H-1,2,4-triazolo[2,3-c][1,3]benzodiazepine.
