Reaction Steps
α-Acetyl-4-fluorophenylacetonitrile (65.1 g) and methylhydrazine (30.9 mL) were dissolved in ethanol (320 mL), and the mixture was heated under reflux for 3 hrs. After the completion of the reaction, the reaction mixture was cooled to room temperature, and the solvent was evaporated. The obtained solid was collected by filtration and washed with hexane to give 5-amino-4-(4-fluorophenyl)-1,3-dimethylpyrazole (69.5 g).
