Methylhydrazine → HCID 57280465, compound

Participants

Reaction Steps

0.11 g (0.05 mol) of 3,4-dihydroxybenzoic acid, ethyl ester and 106 ml of methylhydrazine (2 mol) were refluxed for 3 days. The reaction mixture was evaporated in vacuo and the oily residue treated with ethanol and evaporated again. This was repeated once more. After retreatment with ethanol, 3,4-dihydroxybenzoic acid, 1-methylhydrazide began to crystallize. The crude product was removed by filtration and recrystallized from ethanol; yield: 3.8 g, melting point 202°-205° C.
