    摘要: This invention relates to compounds of the formula ##STR1## where X is --NH, oxygen, N-loweralkyl, or N-arylloweralkyl; R.sub.1 is hydrogen, loweralkyl, cycloalkyl, aryl, arylloweralkyl, loweralkylene, haloloweralkyl, heteroaryl selected from the group consisting of thienyl, furanyl, pyrrolyl and pyridinyl; heteroarylloweralkyl, heterocyclic selected from piperidinyl, piperazinyl, pyrrolidinyl; or heterocyclicloweralkyl; R.sub.2 is hydrogen or loweralkyl; R.sub.3 is loweralkyl or arylloweralkyl; R.sub.4 is hydrogen, loweralkyl, loweralkenyl, loweralkynyl, arylloweralkyl, formyl, loweralkylcarbonyl, arylloweralkylcarbonyl or loweralkoxycarbonyl; Y is hydrogen, loweralkyl or loweralkoxy, and the pharmaceutically acceptable acid addition salts thereof, and where applicable, the geometric and optical isomers and racemic mixtures thereof. The compounds of this invention are useful in the treatment of memory impairment characterized by a cholinergic deficit such as that associated with electroshock-induced amnesia and Alzheimer's disease and other senile dementia.
