실험 절차
To a solution of benzylhydrazine hydrochloride (11.1 g, 57.1 mmol) in water (100 mL) was added dropwise a solution of pyruvaldehyde (10.3 g, 9.3 mL, 57.1 mmol) in water (500 mL). The mixture was stirred at room temperature overnight. The reaction mixture was diluted with CH2Cl2 (4×150 mL). The combined organic extracts were washed with saturated aqueous NaCl, dried over Na2SO4, filtered and concentrated to provide 2-oxopropanal benzylhydrazone (10.1 g, 100%).
