[5-Aroyl-5,6-dihydro-4H-pyrrolo[1,2-a][1,4]benzodiazepin-4-carboxylic acids: synthesis and analgesic and neurobehavioral activity]. / Acidi 5-aroil-5,6-diidro-4H-pirrolo[1,2-a][1,4]benzodiazepin-4-carbossilici: sintesi ed attività analgesica e neurocomportamentale.

Reaction between 1-(2-aminomethylphenyl)-1H-pyrrole hydrochloride and methyl 2-methoxyglicolate in methanol afforded methyl 5,6-dihydro-4H-pyrrolo[1,2-a][1,4]benzodiazepin-4-carboxylate. Aroylation at the 5-position and subsequent hydrolysis of the ester function led to 5-aroyl-5,6-dihydro-4H-pyrrolo[1,2-a][1,4]benzodiazepin-4-ca rboxylic acids. The pharmacological profile of these acids has been studied with regard to analgesic, antiinflammatory and neuropsychobehavioural effects.
