Reaction Steps
A mixture of 6-(3-acetamido-4-chlorophenyl)-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one (34.75 g) and 100% hydrazine hydrate (100 ml) was heated at 100° C. for 3 hours. After cooling, the resulting crystals were recovered by filtration and washed with aqueous methanol to give 6-(3-amino-4-chlorophenyl)-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one (28.04 g).
