Sharma, Suresh Chandra published the artcileSynthesis, reactions, and nuclear magnetic resonance spectroscopy of 4-methyl-6H-pyrazolo(3,4-b)azepin-7-ones, Quality Control of 3553-12-6, the publication is Canadian Journal of Chemistry (1979), 57(23), 3034-40, database is CAplus.
I (R = H, Me, Ph, halogenated phenyl; R1 = H, Me) reacted with Et levulinate to give II (same R, R1) and acetamidopyrazoles. The courses of methylation and bromination of some II were examined; conversion of one pyrazoloazepinone to 7-chloropyrazoloazepine and amination gave 7-(substituted amino)pyrazoloazepines. Structural assignments, tautomeric preferences, and through-space interactions between substituents were established through NMR (1H and 13C). Some II exhibit significant antiinflammatory and analgesic effects in mice.
