In a manner similar to that of Example 4, condensation of 1-hydrazino-3,4-dihydroisoquinoline (7 g.) and benzaldehyde (5.5 g.) and treatment of the reaction mixture with hydrochloric acid gave a solid, which was recrystallized from ethanol-ether, affording 1-(2-benzylidenehydrazino)-3,4-dihydroisoquinoline (I: X=C6H5, X'=Y=Y'=Z=Z'=H) hydrochloride (11.6 g., m.p. 226°-228° C.).
