In a manner similar to that of Example 4, condensation of 1-hydrazino-3,4-dihydroisoquinoline (7.3 g.) and α-methylcinnamaldehyde (6.56 g.) and treatment of the reaction mixture with hydrochloric acid gave a solid, which was recrystallized first from ethanol-ether, then twice from N,N-dimethylformamide-ether, affording 1-[2-(2-methyl-3-phenylallylidene)hydrazino]-3,4-dihydroisoquinoline (I: X=C6H5CH=C(CH3), X'=Y=Y'=Z=Z'=H) hydrochloride in two crops (5.6 g. and 4.2 g., m.p. 217°-219° C.).
