Resumen

New 4-Aryl-6-methyl-8-phenyl-2,3-dihydropyrazolo3,4-bdiazepines and 4-aryl-8-methyl-6-phenyl-2,3-dihydropyrazolo4,3-bdiazepines were obtained from the reaction of 4,5-diamino-3-methyl-1-phenylpyrazole 1 with one equivalent of the 3-dimethylaminopropiophenones 2 in absolute ethanol. The structures of 4-aryl-6-methyl-8-phenyl-2,3-dihydropyrazolo3,4-bdiazepines 3 and 4-aryl-s-methyl-6phenyl-2,3-dihydropyrazolo4,3-bdiazepines 4 were determined by detailed nmr measurements.Nota general
