VERFAHREN ZUR HERSTELLUNG VON SUBSTITUIERTEN AMINOTRIAZINEN

摘要

The present invention provides compounds of the formula (I) wherein R<6> is chlorine, bromine, iodine, C1-4 alkyl or trifluoromethyl; R<7> is hydrogen, halogen, C1-4 alkyl or trifluoromethyl or R<6> and R<7> form a -CH=CH-CH=CH- group optionally substituted by a halogen atom or a C1-4 alkyl or trifluoromethyl group; R<8> is hydrogen, halogen, C1-4 alkyl or trifluoromethyl; R<9> is hydrogen, halogen, C1-4 alkyl or trifluoromethyl, and R<1><0> is hydrogen, methyl or fluorine, provided that at most only two of R<7>-R<1><0> are other than hydrogen and that R<7>-R<1><0> are not all hydrogen when R<6> is chlorine, which are useful as intermediates for the preparation of compounds of formula (II) wherein R<6>, R<7>, R<8>, R<9> and R<1><0> are as defined in claim 1 and R<1><1> is amino, C1-4 acylamino or di-substituted aminomethyleneamino, being useful in the treatment of CNS disorders such epilepsy.
