N-Phenyl-p-phenylenediamine → HCID 9814010, compound

Participants

Reaction Steps

A mixture of 1.84 g (10 mmoles) of N1-phenyl-1,4-benzenediamine and 0.41 ml (5 mmoles) of α-bromo-γ-butyrolactone in 20 ml of acetonitrile is heated under reflux for 5 hours. After returning to 20° C., the precipitate which appears during the reaction (N1-phenyl-1,4-benzenediamine hydrobromide) is filtered and rinsed with 20 ml of acetonitrile. The filtrate is concentrated to dryness under vacuum and the residue is purified on a silica column (eluent: Heptane/AcOEt: 1/1 to 4/6). Beige powder. Melting point: 142.5-143° C.
