Compounds of the formula ##STR1## wherein Ar is phenyl; mono- or di-substituted phenyl, where the substituents are one to two halogens, one to two alkyls of 1 to 3 carbon atoms, or one amino, nitro, cyano or trifluoromethyl; or pyridinyl; R is hydrogen, chlorine, methyl or methoxy; R.sub.1 is hydrogen or methyl; R.sub.2 is hydrogen, alkyl of 1 to 6 carbon atoms, alkenyl of 2 to 6 carbon atoms, alkynyl of 2 to 6 carbon atoms, cycloalkyl of 3 to 8 carbon atoms, methyl-(cycloalkyl of 3 to 8 carbon atoms) or --A--R.sub.4, where A is alkylene of 2 to 3 carbon atoms, and R.sub.4 is hydroxyl, methylamino, dimethylamino, N-methyl-ethylamino, diethylamino, pyrrolidino, piperidino, hexamethyleneimino, morpholino or 4-methyl-1-piperazinyl; or R.sub.1 and R.sub.2, together with each other and the nitrogen atom to which they are attached, form a 4- to 7-membered, saturated or mono-unsaturated, unsubstituted or substituted heterocycle which may contain nitrogen, oxygen, sulfur, sulfinyl or sulfonyl as additional ring members, where the substituents are alkyls of 1 to 3 carbon atoms. The compounds are useful as anticonvulsants.
