80 g (0.316 mol) of N-isobutylidene-3-phenoxybenzylamine is dissolved in 80 ml of toluene; to the solution is then added 4 g (0.036 mol) of potassium-tert-butylate, and the mixture is refluxed for 4 hours. After cooling of the reaction mixture, 35 g of 37% hydrochloric acid (about 0.35 mol) and 50 ml of water are added, and the toluene phase is separated. The toluene is distilled off to leave 57 g (0.288 mol) of 3-phenoxybenzaldehyde, corresponding to a yield of 91% of theory.
