반응 단계
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.
