Abstract
The invention relates to substituted 5-benzyl-2,4-diaminopyrimidines of general formula (A) wherein R1 is C2-C3 alkyl an R2 is heterocyclyl, phenyl or naphthyl, bonded by one of its C-atoms and R3 is C2-C6 alkyl, alkenyl, cycloalkyl, cycloalkylalkyl, heterocyclylalkyl, alkylsulfonyl, cycloalkylsulfonyl, cycloalkylalkylsulfamoyl, heterocyclysylfonyl, heterocyclylalkylsulfonyl or dialkylsulfamoyl; wherein alkyl, cycloalkyl and alyenyl can carry up to 6 carbon atoms alone or in compositions and can carry up to 6 ring members heterocyclically, alone, or in compositions and the groups R2 and R3 can be substituted; and to acid addition salts of compounds. The invention also relates to a method for producing the above 5-benzyl-2,4-diaminopyrimidines, to the intermediate. products that are produced, to corresponding medicaments and to the use of 5-benzyl-2,4-diaminopyrimidines as medicinal preparations. The products have antibiotic properties and are useful for combating or preventing infectious diseases.
