Benzaldehyde, 4-(phenylmethoxy)- → 4-Benzyloxy-benzaldehyde oxime

참여 물질

반응 단계

4.24 g of 4-benzyloxy benzaldehyde (20 mmol) was dissolved in a 0.2M mixed solution of ethanol and water (3:1,100 ml), followed by stirring. 2.78 g of NH2OH—HCl (40 mmol) and 2.46 g of sodium acetate(30 mmol) were added thereto, and stirred at room temperature for about 30 minutes. Subsequently, the completion of the reaction was confirmed by liquid chromatography, and water and ethanol were removed by distillation under reduced pressure to obtain a pale yellow solid compound. The pale yellow solid compound was extracted three times with water and ethyl acetate, an organic solvent layer was dried under reduced pressure to obtain a crude product, and the crude product was then purified with a hexane/ethylacetate solution (10:1) to obtain a white solid compound. The obtained solid compound was subjected to subsequent reactions without additional purification.
