Reaction Steps

To 3-(methylthio)-6-phenyl-1,2,4-triazin-5(4H)-one (4.3 g) in isopropyl alcohol (40 mL) was added hydrazine (6.41 g, 0.200 mol). The reaction mixture was refluxed for 10 h. After cooling, the crystalline solid formed was filtered and washed with isopropyl alcohol. The crystalline solid was collected and dried in vacuo to afford the desired product. Analytical LCMS: (M+H)+=204.1.
