New aralkylaminoquinazolines have formula (I), in which m equals 0, 1, 2, 3 or 4; n equals 1, 2, 3 or 4; R<2> stands for hydrogen, halogen, cyano, nitro, carboxy, carbamoyl or possibly halogen-substituted alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, dialkylamino, dialkylaminocarbonyl or dialkylaminosulfonyl with up to 6 carbon atoms in the alkyl residues; R<2> stands for hydrogen or alkyl with up to 6 carbon atoms; R<3> stands for hydrogen, alkyl or possibly halogen-substituted alkylcarbonyl or alkylsulfonyl with up to 6 carbon atoms in the alkyl groups; R<4> stands for hydrogen or possibly halogen-substituted alkyl with up to 6 carbon atoms; and R<5> stands for halogen, cyano, nitro or possibly halogen-substituted alkyl with up to 6 carbon atoms. Also disclosed are their acid addition salts and metallic salt complexes, with the exception of the compounds S-(+)-7-chloro-N-(1-phenyl-ethyl)-4-quinazolinamine and R-(-)-7-chloro-N-(1-phenyl-ethyl)-4-quinazolinamine, a process for preparing the same and their use as fungicides. |
