Reaction Steps

In formic acid (85.5 ml) was dissolved 5-bromo-2-ethoxybenzaldehyde (17.1 g). To the mixture was added hydroxylamine hydrochloride (7.8 g), and the mixture was refluxed for 7 hours and cooled to room temperature. Under reduced pressure, the solvent was evaporated, and the residue was washed with water and dried to give 5-bromo-2-ethoxybenzonitrile (15.8 g).
