Abstract: By modifying some conditions during the prepn. from AcNHPh and refluxing by superheated H₂O in vacuo, o-nitroaniline (I), m. 72.5°, was obtained in 60.0-3.4% yield and the time of prepn. was shortened to 12 hrs. From I by reduction with H and with Raney Ni as catalyst was obtained 90-5% o-C₆H₄(NH₂)₂, m. 103°.
