반응 단계
A mixture of 6.11 gm (0.05 mole) of 2-acetylpyrazine, 4.41 gm (0.05 mole) of propanoic acid hydrazide and 100 ml of absolute ethanol is refluxed 10 hr. The mixture is cooled. The white crystals which deposit are collected and dried to yield 6.17 gm (64%) of the title compound having a melting point of 181.3° C.
