To a solution of 25 g (150 mmol) 5-hydroxy-2-nitro-benzaldehyde and 44.8 g (299 mmol) sodium iodide in 400 ml acetone are added 51.2 ml (299 mmol) N-ethyldiisopropylamine and 25.3 ml (299 mmol) allyl bromide. After stirring for 18 h at r.t. the reaction mixture is filtered and the solvent is evaporated. Extraction of the residue with 1 M aqueous hydrochloric acid/dichloromethane followed by chromatography (hexane/ethyl acetate) yields 5-allyloxy-2-nitro-benzaldehyde.
