実験手順
C.hydrochloric acid (1 drop) was added to a stirred solution of 3-hydrazino-5-methyl-6-phenyl-1,2,4-triazine (4.12 g) and propionaldehyde (4 ml) in methanol (15 ml) at room temperature, and the stirring was continued for 5 minutes. The reaction mixture was evaporated and the resultant residue was triturated with diethyl ether. The precipitates were collected by filtration to give 5-methyl-6-phenyl-3-(2-propylidenehydrazino)-1,2,4-triazine (3.89 g).
