ABSTRACT:
A method of effecting a one-pot conversion of a tetrahydronaphthalic anhydride of formula (I):to a nitrate salt of a benzisoindolenine of formula (II):The method comprises heating the tetrahydronaphthalic anhydride of formula (I) with a reagent mixture comprising ammonium nitrate so as to effecting concomitant dehydrogenation during the conversion.
