Synthesis of derivatives of pyrazolo[1,5‐ a ]pyrrolo[1,2‐ c ][1,3,6]‐benzotriazocine, a new class of compounds with potential CNS activity

The synthesis of derivatives of pyrazolo[1,5‐ a ]pyrrolo[1,2‐ c ][1,3,6]benzotriazocine was obtained by the reaction of arylaldehydes with some 1‐(2‐aminophenyl)‐5‐(pyrrol‐1‐yl)pyrazoles, as hydrochlorides. Characterization of this new class of compounds was effected with ir, pmr and 13 C nmr spectral data.
