Abstract

Patente de Invenção: <B>"PROCESSO DE PREPARAçãO DE COMPOSTOS DE TIPO 4-(ALQUIL)-3-ALCóXI-ANILINAS''<D>. A presente invenção refere-se a um processo de preparação de um composto de fórmula (I), na qual: R¹ representa um grupo alquila, linear ou ramificado, em C~ 1~-C~ 10~, um grupo aralquila no qual a parte alquila é linear e compreende de 1 a 3 átomos de carbono e a parte arila é escolhida dentre os grupos fenila, substituídos ou não, notadamente por um ou vários grupos alquilas em C~ 1~ a C~ 3~, por um ou vários átomos de halogênio ou por um ou vários grupos radicais nitro. R² representa um grupo alquila, linear ou ramificado em C~ 1~-C~ 16~. Os compostos de fórmula (I) são intermediários de síntese úteis notadamente para a preparação de derivados de quinoleína ou de quinolona tais como os ésteres de ácidos 4-hidroxiquinoleína-3-carboxílicos.Invention Patent: <B> "PROCESS OF PREPARING COMPOUNDS OF TYPE 4- (ALKYL) -3-ALKOXY-ANYLINES '' <D>. The present invention relates to a process of preparing a compound of formula (I ), in which: R¹ represents an alkyl group, linear or branched, in C ~ 1 ~ -C ~ 10 ~, an aralkyl group in which the alkyl part is linear and comprises from 1 to 3 carbon atoms and the aryl part is chosen from among the phenyl groups, whether or not substituted, notably by one or more alkyl groups in C ~ 1 ~ to C ~ 3 ~, by one or more halogen atoms, or by one or more nitro radical groups. R² represents an alkyl group, linear or branched at C ~ 1 ~ -C ~ 16 ~ The compounds of formula (I) are useful synthetic intermediates, notably for the preparation of quinoline or quinolone derivatives such as esters of 4-hydroxyquinoline-3-carboxylic acids .
