Abstract

A compound of the formula: ##STR1## in which R.sup.1 and R.sup.2 are, independently, hydrogen, alkyl of 1 to 6 carbon atoms, alkoxy of 1 to 6 carbon atoms, halo, perfluoroalkyl of 1 to 3 carbon atoms, nitro, alkanoyl of 2 to 4 carbon atoms or alkoxycarbonyl of 2 to 4 carbon atoms; R.sup.3 is hydrogen, halo, nitro or alkanoyl of 2 to 4 carbon atoms; R.sup.4 is hydrogen, halo, nitro or perfluoroalkyl of 1 to 3 carbon atoms; R.sup.5 and R.sup.6 are, independently, hydrogen or methyl; and R.sup.7 and R.sup.8 are, independently, alkyl of 1 to 4 carbon atoms, or when taken with the nitrogen atom to which they are attached form a piperidinyl, pyrolidinyl, morpholinyl, N-alkyl piperazinyl in which the alkyl group contains from 1 to 6 carbon atoms or N-phenylpiperazinyl group or a non-toxic acid addition salt thereof, are central nervous system stimulants.
