Participants

Reaction Steps

A solution of acetylacetone (2.415 g) in methanol (10 ml) was added to a mixture of 6-(4-chlorophenyl)-3-hydrazino-5-methyl-1,2,4-triazine (4.946 g) and acetic acid (3 drops) in methanol (20 ml), and the solution was refluxed for 2 hours with stirring and allowed to stand at room temperature. The resultant crystals were collected by filtration, washed with cold methanol, and dried to give 6-(4-chlorophenyl)-3-(3,5-dimethylpyrazol-1-yl)-5-methyl-1,2,4-triazine (5.354 g), m.p. 151° to 152.5° C.
