Nicotinic acid, hydrazide → Nicotinic acid (4-quinolinylmethylene)hydrazide

Participants

Reaction Steps

A mixture of 7.86 gm (0.05 mole) of 4-quinolinecarboxaldehyde, 6.86 gm (0.05 mole) of nicotinic acid hydrazide and 100 ml of ethanol is refluxed 2 hr. The reaction mixture is cooled to room temperature. The solid which sepatates is collected, washed with water and dried; 14.4 gm (quantitative) to give the title compound; mp. 99.6° C. The product is recrystallized from ethanol to give 11.54 gm (83%) of the title compound, having a melting point of 192.7° C.
