Procedure

100 ml of aqueous 10% sodium hydroxide solution were added to an aqueous solution (50 ml) of 14.55 g of (2-phenylethyl)hydrazine sulfate, and 2.25 g of sodium hydroxide were added thereto and stirred at room temperature for one hour. The reaction solution was extracted with 250 ml of dichloromethane, dried over magnesium sulfate, concentrated under reduced pressure and dried. The resulting residue was dissolved in 100 ml of ethanol, and 5.55 g of benzaldehyde were added thereto and heated under reflux for 6 hours. This reaction solution was concentrated under reduced pressure and dried to obtain 11.38 g of a crude product of the intended compound as an yellow oil.
