To a solution of 27.6 g. of 5-(o-fluorophenyl)-3-(methylthio)-1,2,4-triazine in 100 ml. of 1:1 methanol-tetrahydrofuran is added 6.4 ml. of 95% hydrazine. The mixture is refluxed for about 22 hours and then cooled. The solid is recovered by filtration, giving 5-(o-fluorophenyl)-3-hydrazino-1,2,4-triazine as yellow crystals.
