반응 단계
90 g (0.6 mole) of salicylic acid hydrazide and 355.2 g (2.4 moles) of orthoformic acid ethyl ester are refluxed for 22 hours. Excess of the ester is distilled off and the solid residue is recrystallized from ethanol. 62.9 g of colorless crystals (64.7% of theory) are obtained; melting point 112°-113° C.
