Abstract
A process for the preparation of substituted 3-dialkylaminoalkoxy-indazoles in position 1, of the general formula (I) ** (See formula) ** in which: R is hydrogen or chlorine; R 'is a lower alkyl radical or an aryl or aralkyl group which may or may not be substituted in its aryl nucleus by halogen atoms or lower alkoxy or alkoxyls radicals; R "is hydrogen or a lower alkyl radical; the R '' ', which may be identical or different, are lower alkyl radicals; n is the number 1 or the number 2, said process being characterized by the fact that anthranilic acids or esters having the general formula ** (See formula) ** wherein R and R 'have the meanings specified above, and R' '' is hydrogen or a lower alkyl radical, preferably the methyl radical, with nitrates, the nitrated derivatives obtained are reduced by a hydrosulfite, and the -hydroxy-indazoles which are prepared in this way, of the general formula: ** (See formula) ** wherein R and R 'have the meanings specified above, they are reacted with halogenoalkoyl dialkyl amines of the general formula ** (See formula) ** wherein R ", R" 'and n have the meanings specified above, and "Hal" is a halogen atom, preferably a chlorine atom.
