Sulfuric Acid → HCID 12349072, compound

Participants

Reaction Steps

In a manner similar to that of Example 4, condensation of 1-hydrazino-3,4-dihydroisoquinoline (9.4 g.) and cyclohexanone (6.3 g.) and treatment of the reaction mixture with sulfuric acid gave an oil, which was crystallized, then recrystallized, from isopropyl alcohol-ether, affording 1-(2-cyclohexylidenehydrazino)-3,4-dihydroisoquinoline [(I: X=X'=CH2 (CH2)4C,] Y=Y'=Z=Z'=H) sulfate (15.3 g., m.p. 139°-141° C. with decomposition).
