Participants

Reaction Steps

A solution of methyl 3-oxo-2-{[3-(trifluoromethyl)phenyl]hydrazono}pentanoate (4.00 g, 13.2 mmol) in N,N-dimethylformamide dimethylacetal (33 mL) was heated at reflux for 2.5 hours. After that time, the reaction was cooled to room temperature and the resulting solid was collected by filtration and washed with a small amount of hexanes to give methyl 5-methyl-4-oxo-1-[3-(trifluoromethyl)phenyl]-1,4-dihydropyridazine-3-carboxylate (3.55 g, 87%) as a pale yellow solid.
