Abstract

"PROCESSO PARA PREPARAçãO DE 2-AMINO-5,8-DIMETóXI [1,2,4] TRIAZOLO [1,5-C] PIRIMIDINA". A presente invenção refere-se a um processo para a preparação de a qual 2-amino-5,8-dimetóxi [1,2,4] triazolo [1,5-c] pirimidina é preparada a partir de 3-amino-8-metóxi-[1,2,4] triazolo [4,3-c]pirimidina substituída com 5-cloro ou 5-metóxi por reação com metóxido em um solvente álcool. Tanto o rearranjo como, quando o substituinte é cloro, a substituição com metóxi podem ser realizados diretamente.
