실험 절차
To a solution of 4-formyl-3-hydroxy-benzonitrile (CAS 84102-89-6) (6.90 g) in dry ethanol (165 ml) was added sodium acetate (4.23 g) and hydroxylamine hydrochloride (3.58 g). The mixture was stirred at rt for 1 h. The solvent was evaporated and the product was purified by flash chromatography (cyclohexane/EtOAc 8:2=>1:1) to give 3-hydroxy-4-(hydroxyimino-methyl)-benzonitrile (4.70 g). Light yellow solid. MS 162.0 ([M]+)
