Procedure
A mixture of 2,6-dichloro-phenylhydrazine hydrochloride (11.7 g, 54.8 mmol) in 1 M NaOH (55 mL), brine (200 mL) and saturated sodium bicarbonate (100 mL) was extracted with dichloromethane (3×200 mL). The organic layers were combined, dried (sodium sulfate), filtered and evaporated to give 2,6-dichloro-phenylhydrazine (9.88 g, quantitative).
