実験手順

A mixture of 5-bromosalicylaldehyde (1.01 g, 5 mmol), 3,5-dichloroaniline (810 mg, 5 mmol) and ethanol (25 mL) was refluxed for 1 hour under argon atmosphere. After the reaction mixture was cooled to room temperature, the separated crystal was filtered to give 3,5-dichloro-N-(5-bromo-2-hydroxybenzylidene)aniline (1.52 g, 88.2%) as an orange crystal.
