There are disclosed novel compounds of the formula ##STR1## where X is H, halogen, loweralkyl, loweralkoxy, --CF.sub.3, or --OH; R is H, loweralkyl, arylloweralkyl, diarylloweralkyl, loweralkanoyl, arylloweralkanoyl or diarylloweralkanoyl; and R.sub.1 is H.sub.2, O or --NR.sub.2 R.sub.3, R.sub.2 and R.sub.3 being independently H or loweralkyl, or taken together with the nitrogen atom to which they are attached constitute ##STR2## R.sub.4 in turn being H, loweralkyl, hydroxyloweralkyl, aryl, arylloweralkyl or diarylloweralkyl or pharmaceutically acceptable acid addition salts thereof, which are useful for enhancing memory.
