This application is a continuation-in-part of pending U.S. patent application Ser. No. 388,437, filed Aug. 2, 1989. This invention relates to 1,3-dihydro-1-(pyridinylamino)-2H-indol-2-ones of the formula ##STR1## where R.sub.1, R.sub.2 and R.sub.3 are independently hydrogen, loweralkyl, aryl, arylloweralkyl or heteroarylloweralkyl selected from the group consisting of pyridinylmethyl, pyridinylethyl, thienylmethyl, thienylethyl; or R.sub.2 and R.sub.3 together form a cycloalkane ring or 4 to 6 carbons or a spiro-fused aryl cycloalkane or heterocycloalkyl selected from the group consisting of piperidine and tetrahydropyran; X and Y are independently hydrogen, halogen, hydroxy, loweralkyl, loweralkoxy, nitro, amino or trifluoromethyl; m and n are independently integers of 1 to 3, the pharmaceutically acceptable acid addition salts thereof and, where applicable the optical, geometrical and stereoisomers and racemic mixtures thereof. The compounds of this invention display utility as analgesics, anticonvulsants, for enhancing memory and for the treatment of Alzheimer's disease.
