실험 절차
A solution of 22 parts glyoxylic acid in 22 parts water is slowly added to a hot, stirred solution of 32 parts thiocarbohydrazide in 350 parts water. The resulting mixture is refluxed until no further precipitate is formed. Upon cooling, essentially pure 4-amino-2,3-dihydro-3-thiono-as-triazin-5(4H)-one having a melting point of 211°-215° C. is obtained by filtration.
