実験手順

A mixture of 9.16 gm (0.05 mole) of 4-benzoyl pyridine, 6.86 gm (0.05 mole) of nicotinic acid hydrazide, 100 ml of ethanol and 4.4 ml of concentrated hydrochloric acid was refluxed 16 hr. The reaction mixture was cooled to room temperature. An equal volume of water was added containing 5.4 gm (0.05 mole) of sodium carbonate. The mixture was placed in the refrigerator. The product which separated was collected, washed with water and dried to give 8.21 gm (54%) of the title compound having a melting point of 74.0° C.
