Reaction Steps

3-Chloro-4-methyl-6-phenylpyridazine (0.510 g, 2.49 mmol) was dissolved in hydrazine (1.56 ml, 49.8 mmol) then the reaction mixture was heated at 100° C. for 1.5 hours. The precipitate that had formed in the mixture was collected and washed with iPrOH. The solid was dried under high vacuum to afford 1-(4-methyl-6-phenylpyridazin-3-yl)hydrazine as a pale yellow solid.
