Reaction of antipyrine with Schiff bases

New dihydropyrazolone derivatives were prepared by condensation of antipyrine with substituted arylmethyleneanilines or arylmethylene-2- naphthylamines. Pleiades Publishing, Inc., 2006.

Solvent-free condensation of aromatic aldehydes and 2,3-dimethyl-1-phenyl-3-pyrazolin-5-one by p-toluenesulfonic acid

Solvent-free condensation easily occurred by mixing aromatic aldehydes and 2,3-dimethyl-1-phenyl-3-pyrazoline-5-one (antipyrine) in the presence of p-toluenesulfonic acid as a solid acid catalyst at room temperature to give the corresponding disubstituted
