実験手順

In a solution of 5.0 g of 3-chloro-4-methylbenzaldehyde in 40 mL of methanol and 30 mL of water, 4.7 g of hydroxylamine hydrochloride was added, and stirred at room temperature for 2 hours. After the completion of the reaction, the reaction mixture was diluted with 70 mL of ethyl acetate, washed with water (30 mL×1), and then dehydrated with and dried over saturated sodium chloride and anhydrous sodium sulfate in that order, and the solvent was distilled off under reduced pressure to obtain 5.1 g of the aimed product as white crystal. The resulting product was used as such without purification for the next step.
