Reaction Steps
After dissolving 3,4-dimethoxybenzaldehyde (1.00 g, 0.081 mmol) in 60 mL of ethyl alcohol/water (1/1, v/v) solution, H2NOH HCl (0.54 g, 7.823 mmol) was added. While stirring the reaction mixture, Na2CO3 (0.83 g, 7.823 mmol) was added slowly at below 0° C. The reaction was continued for 1 hr in an oil bath preheated to 60-65° C. After the reaction was completed, 1.05 g (96.4%) of the target product was obtained by extracting with ethyl acetate, drying over anhydrous MgSO4 and removing the solvent under reduced pressure.
