Versuchsvorschrift

4 N hydrogen chloride-ethyl acetate (2 mL) was added to a suspension of tert-butyl N′-((S)-2-phenylpropionyl)hydrazinecarboxylate (470 mg) in ethyl acetate (4 mL), and the reaction solution was stirred at room temperature overnight. Diethyl ether (6 mL) was added to the reaction solution, and the precipitated powder was collected by filtration. The resulting solid was dried under reduced pressure to obtain 280 mg of the title compound. The property values of the compound are as follows.
