Abstract: Racemates and optically active isomers of a compound selected from the group consisting of a compound of the formula ##STR1## wherein R is selected from the group consisting of hydrogen, lower alkyl optionally substituted with a member of the group consisting of hydroxy and halogen, lower alkenyl, lower alkynyl, --(CH.sub.2).sub.n -- COCH.sub.3 where n is 0 or 1, ##STR2## wherein X is selected from the group consisting of lower alkyl and optionally substituted phenyl, aralkyl or 7 to 8 carbon atoms, acyl of an organic carboxylic acid of 1 to 6 carbon atoms optionally substituted with ##STR3## where m is an integer from 0 to 6 and X.sub.1 is selected from the group consisting of hydrogen and lower alkyl, ##STR4## where p is an integer from 1 to 6 and X.sub.1 is as before and ##STR5## wherein X.sub.2 is lower alkyl and R.sub.1 and R.sub.2 are individually selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, trifluoromethyl and dilower alkylamino and the non-toxic, pharmaceutically acceptable acid addition and quaternary ammonium salts thereof which have a stimulating effect on the central nervous system while possessing at the same time anticonvulsant activity and their preparation.
