実験手順
2.2 g of 3-pyridinecarbaldehyde was dissolved in 100 ml of ethanol. The solution was added to a filtered solution of 3.6 g of p-chlorophenylhydrazine hydrochloride and 9.8 g of sodium acetate in 60 ml of 50% by volume aqueous ethanol. The resulting precipitated solid was collected and recrystallized from ethanol to give 1, as a pale yellow prisms, mp 186° C.
