실험 절차
In 50 ml of methanol was suspended 22 g of nicotinic acid hydrazide. To the suspension was added dropwise 13.2 ml of crotonaldehyde, followed by stirring for 30 minutes at room temperature. Methanol was distilled away under reduced pressure, and the residue washed with ether, filtered off, and dried. Thus there was obtained 27.5 g of crotonaldehyde nicotinoyl hydrazone (mp. 144°-145° C.).
