实验步骤: A solution of N-benzyloxyacetamide (1.65 g, 10 mmol) in 10 ml of dimethylformamide was cooled down in an ice bath, 60% sodium hydride (0.4 g, 10 mmol) was added thereto, and stirred for 10 minutes. After adding dropwise 20 ml of dimethylformamide solution of 2-bromomethylphenyl-3-methoxypropenoate (2.85 g, 10 mmol), the solution was allowed to react for 15 hours at room temperature. After completion of the reaction, the reaction solution was poured into 200 ml of water, and extracted with ethylacetate. The organic layer was rinsed with water and dried. After removing the solvent by evaporation, the residue was purified with silica gel chromatography to obtain 0.34 g of methyl 2-[2-(1-benzyloxyiminoethyl) oxymethylphenyl]-3-methoxypropenoate (yield: 9.2%). The proton NMR spectrum is 1.79 s (3H); 3.67 s (3H); 3.77 s (3H); 5.01 s (2H); 5.04 s (2H); 7.10-7.50 m (9H); 7.57 s (1H) (solvent: CDCl3). to react for 15 hours at room temperature After completion of the reaction extracted with ethylacetate The organic layer was rinsed with water dried After removing the solvent by evaporation the residue was purified with silica gel chromatography

实验步骤: 60% sodium hydride (11.68 g, 0.292 mol) was added to a dimethylformamide solution (200 ml) of acetohydroxamic acid (21.9 g, 0.292 mol) with cooling in an ice bath. After stirring for 1 hour at room temperature, benzylbromide (50 g, 0.292 mol) was added thereto and allowed to react for 24 hours at room temperature. The reaction solution was poured into 500 ml of water, and extracted with ethyl acetate. The organic layer was rinsed with water and dried. After removing the solvent by evaporation, the residue was purified with silica gel chromatography to obtain 31.3 g of N-benzyloxyacetamide (yield: 65%). The proton NMR spectrum of the compound is 1.85 s (3H); 4.89 bs (2H); 7.37 s (5 H); 8.30 bs, 8.81 bs (1H) (solvent: CDCl3). with cooling in an ice bath to react for 24 hours at room temperature extracted with ethyl acetate The organic layer was rinsed with water dried After removing the solvent by evaporation the residue was purified with silica gel chromatography
