実験手順: A mixture of 6.45 g 5-bromo-o-anisaldehyde, 2.2 g of hydroxylamine hydrochloride, 4.1 g of sodium formate and 20 mL formic acid were heated at 100° C. with stirring for 1 h. The reaction mixture was poured onto ice water and the mixture was made basic by the careful addition of 50% sodium hydroxide. The product was extracted with ether, the ether extracts were dried over magnesium sulfate and the solvent was removed in vacuo. The residue was crystallized from ether/hexane to afford 5-bromo-2-methoxybenzonitrile. The reaction mixture was poured onto ice water The product was extracted with ether the ether extracts were dried over magnesium sulfate the solvent was removed in vacuo The residue was crystallized from ether/hexane
