Methanol → HCID 70392212, compound

Participants

Reaction Steps

187 g of the β-(2-benzofuryl)acrylic acid cyanomethyl ester were added to 2 liters of methanol, and to the mixture, with stirring, were added 76.8 g of hydrazine hydrate, and then the resulting mixture was refluxed by heating for 30 minutes. After the reaction, 2 liters of water were added to cool the reaction product, and the deposited crystals were filtered by a suction filter, then washed, and then recrystallized from methanol, thereby obtaining 150 g of β-(2-benzofuryl)acrylic acid hydrazide having a melting point between 173° C. and 174° C.
