A solution of 4-chlorobenzene-1,2-diamine (1.50 g, 10.5 mmol) in EtOH (15 mL) was heated to reflux and selenium dioxide (1.28 g, 11.5 mmol) was added. The reaction was refluxed for 30 min and cooled to ambient temperature. The precipitated solid was filtered, washed thoroughly with H2O and dried under high vacuum to give the title compound. MS: m/z=219 (M+1).
