Abstract

A találmány szerinti eljárás során 2-amino-5,8-dimetoxi[1,2,4]triazolo[1,5-c]pirimidint egy 5-klór vagy 5-metoxi-csoporttalszubsztituált 3-amino-8-metoxi[1,2,4]triazolo[4,3-c]pirimidinbőlállítják elő egy alkoholos oldószerben metoxiddal végzett reakcióval.Mind az átrendeződést, mind az 5-klóratom metoxicsoportra történőszubsztitúcióját közvetlenül kivitelezhetik.
