Procedure
To a solution of 4-bromophenylhydrazine hydrochloride (11.5 g, 50 mmol) in anhydrous ethanol (200 mL) is added 3-acetylpyridine (6.1 g, 50 mmol). The mixture is heated to 90° C. and stirred for 3 h, cooled to room temperature and filtered through a sintered glass funnel. The solid is washed with ethanol and placed under high vacuum overnight to give N-(4-bromo-phenyl)-N′-[1-pyridin-3-yl-eth-(Z)-ylidene]-hydrazine hydrochloride as a yellow solid.
