Reaction Conditions

Reaction Steps

To the white powder of the trimethylacetyl semicarbazide obtained was added 1500 ml of a 5% aqueous potassium hydroxide solution, and the mixture was heated to 100° C. while stirring. After the contents were completely dissolved, the solution was further heated at 100° C. for one hour, and the reaction mixture then cooled and neutralized by an addition of conc. sulfuric acid. The white precipitates formed were collected by filtration, washed with water, and then dried under a reduced pressure to yield 64 g of white powder of 3-tert-butyl-1H-1,2,4-triazole-5-one. (yield 45%)
