Reaction Steps

To a stirred solution of 3-bromobenzaldehyde (22.38 g, 121 mmol) in ethanol (150 mL) was added triethylorthoformate (27 g, 181 mmol) and concentrated HCl (0.5 mL). The mixture was heated to reflux for 3 hours and allowed to cool to ambient temperature. The reaction mixture was poured into ice/H2O and extracted thoroughly with hexanes. The combined organic extracts were washed with water and brine, dried (MgSO4) and concentrated in vacuo to give 34 g of 3-bromobenzaldehyde diethyl acetal as a colorless liquid.
