Abstract 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.
