    摘要: A spiro derivative of the pyrazolo [1,5-d] [1,2,4] triazine ring system of the formula I ##STR1## wherein R.sub.1 and R.sub.2 represent, independently from each other, a hydrogen atom or a C.sub.1-4 alkyl group,R.sub.3 stands for a hydrogen atom, an unbranched or branched C.sub.1-4 alkyl, C.sub.2-5 alkenyl or benzyl group,R.sub.4 represents a hydrogen atom, an unbranched or branched C.sub.1-4 alkyl, C.sub.4-6 cycloalkyl, an unsubstituted or mono-halo or polyhalo benzyl group, andn is a whole number from 4 to 8,wherein R stands for an unbranched or branched C.sub.1-4 alkyl, or C.sub.4-6 cycloalkyl, C.sub.2-5 alkenyl, an unsubstituted or a monohalogeno or polyhalogenobenzyl group, and X represents a halogen or a 4-methyl-phenylsulfonyloxy group. Compounds of the formula I exhibit valuable CNS activities.
