To a solution of butyl-(2,6-diethyl-benzylidene)-amine (1.10 g; 5.06 mmol) in water (20 mL) was added H2SO4 (5.00 ml; 93.80 mmol), and the resulting mixture was heated under reflux for 2 hours. After cooling to RT the mixture was diluted with EtOAc, and washed with water, a 5% aqueous NaHCO3-solution and brine. The organic phase was dried (Na2SO4), filtered and concentrated in vacuo to afford 2,6-diethyl-benzaldehyde (0.72 g).
