Amination of 3-(4-phenylbenzoyl)acrylic acid gives 2N-(arylamino)-3-(4'-phenylbenzoyl)propionic acid 2. Hydrazinolysis of 2 yields the corresponding 6-(4'-bi-phenylyl)-4-(N-arylamino)-2,3,4,5-tetrahydropyridazin-3-one 3. Compounds 3 have also been prepared from hydrazinolysis of Δβ,γ-butenolides 9 which are obtained from dehydration of 2. The lactam lactim dynamic equilibrium of 3 has been chemically investigated.
