Versuchsvorschrift

Alternate procedure: Add triethylamine (23.1 g, 229 mmol) dropwise to a solution of 2,6-dichloro-benzaldehyde (20.0 g, 114 mmol) and hydroxylamine hydrochloride (10.3 g, 149 mmol) in dichloromethane (200 mL). Stir the reaction mixture for 8 h. Add water (200 mL). Separate the phases and extract the aqueous phase with dichloromethane (100 mL). Wash the combined organic phases with water (100 mL). Concentrate the combined organic phases to provide 28.8 g (94%) of the title compound.
