ABSTRACT:
Tbe invention relates to 3H-1,2,3-triazolo[4,5-d]pyrimidine derivatives, especially substituted 3-benzyl-3H-1,2,3-triazolo[4,5-d]-pyrimidines of the general formula ##STR1## in which Ph represents a phenyl radical substituted by halogen, lower alkyl, trifluoromethyl and/or by cyano, R.sub.1 represents a free amino group or an amino group that is substituted aliphatically, cycloaliphatically, cycloaliphatically-aliphatically and/or by acyl, and R.sub.2 represents hydrogen, lower alkyl, a free amino group, or an amino group that is substituted aliphatically, cycloaliphaically, cycloaliphatically-aliphatically and/or by acyl, in free form or in form of a salt, with the proviso, that in a compound of formula I in free form, wherein R.sub.1 represents N,N-di-C.sub.1 -C.sub.6 -alkylamino in which the two N-C.sub.1 -C.sub.6 -alkyl groups may be the same or different, N-mono-C.sub.1 -C.sub.6 -alkylamino or amino, R.sub.2 is other than hydrogen and other than C.sub.1 - C.sub.6 -alkyl, if Ph represents a phenyl radical which is monosubstituted by halogen or by trifluoromethyl, and to compounds of formula I in free form wherein either Ph is o-fluorophenyl, R.sub.1 is N-mono-methylamino or amino, and R.sub.2 is hydrogen or methyl or wherein Ph is o-fluorophenyl, o-chlorophenyl or m-trifluoromethylphenyl, R.sub.1 is N,N-di-methylamino, and R.sub.2 is hydrogen or wherein Ph is m-fluorophenyl, p-fluorophenyl, o-chlorophenyl, o-trifluoromehylphenyl, m-trifluoromethylphenyl or p-trifluoromethylphenyl, R.sub.1 is N-mono-methylamino, and R.sub.2 is hydrogen. These compounds and salts can be used as pharmaceutical active ingredients and can be produced in a manner known per se.
