    Abstract: THE COMPOUNDS AND CERTAIN INTERMEDIATES ARE USEFUL AS CENTRAL NERVOUS SYSTEM STIMULANTS AND ANTI-INFLAMMATORIES. THEY ARE PREPARED BY CONVERTING AN ISOINDOLO(1,2-A)ISOQUINOLINE TO ITS QUATERNARY AMMONIUM SALT BY TREATMENT WITH A LOWER ALKYL HALIDE, E.G. METHYL IODIDE, AND REDUCING THE SALT BY SODIUM IN LIQUID AMMONIA TO CLEAVE THE BOND COMMON TO THE FIVE MEMBERED RING OF THE ISOINDOLO MOIETY AND SIX MEMBERED RING TO THE ISOQUINOLINO MOIETY, THIS FORMING THE NINE MEMBERED N-HETEROCYCLIC RING OD DIBENZ(C,F)AZONINE. FOR EXAMPLE, 2,3-DIMETHOXY-(-METHYL-5,6,7,8-TETRAHYDRODIBENZ(C,F)AZONINE CAN THUS BE PREPARED FROM 2,3-DIMETHOXY-5,6,8,12B-TETRAHYDROISOINDOLO (1,2A)ISOQUINOLINE.
