A method of treatment with compounds having the formula ##STR1## R.sup.1 is hydrogen, C.sub.1-6 -alkyl which may be branched, C.sub.3-7 -cycloalkyl, benzyl, phenyl which may be substituted, acyl, hydroxy, C.sub.1-6 -alkoxy, CH.sub.2 CO.sub.2 R' wherein R' is hydrogen or C.sub.1-6 -alkyl which may be branched, CH.sub.2 CN, CH.sub.2 CONR.sup.IV R.sup.V wherein R.sup.IV and R.sup.V independently are hydrogen or C.sub.1-6 -alkyl, or CH.sub.2 C(.dbd.NOH)NH.sub.2 ; R.sup.2 is hydrogen, benzyl, C.sub.1-6 -alkyl which may be branched, or C.sub.3-7 -cycloalkyl; R.sup.4, R.sup.5, R.sup.6, R.sup.7 independently are hydrogen, C.sub.1-6 -alkyl which may be branched, phenyl, halogen, C.sub.1-6 -alkoxy, NO.sub.2, CN, CF.sub.3, OCF.sub.3, or SO.sub.2 NR"R'" wherein R" and R'" independently are hydrogen, aralkoxy, aralkyl, or C.sub.1-6 -alkyl; or R.sup.6 and R.sup.7 together form an additional 4 to 7 membered ring which may be aromatic or partial saturated and which may be substituted with halogen, NO.sub.2, CF.sub.3, CN, OCF.sub.3, SO.sub.2 NR" R"' wherein R" and R"' independently are hydrogen, aralkoxy, aralkyl, or C.sub.1-6 -alkyl, and R.sup.4 and R.sup.5 have the meanings set forth above, are disclosed, as well as pharmaceutical compositions thereof. Certain of the compounds are novel. The compounds and pharmaceutical compositions containing the compounds are useful in the treatment of central nervous system disorders and especially conditions sensitive to excitatory amino acids.
