Abstract
A process for the preparation of the 3-monoalkylamino-7-dialkylamino-N-alkyl-fonoxazymes-2 of formula VI ** (See formula) ** where R, R ', R' ', R' '' represent simple or branched aliphatic radicals, comprising from 2 to 4 carbon atoms, where R and R 'may be attached in the form of a piperidic or pyrrolidic cycle optionally carrying branches, characterized in that the 5-nitro-benzimidazole is converted by the known processes into a quaternary ammonium salt of the 5-nitro N, N'-dialcohyl benzimidazole of formula II ** (See formula) ** having R '' and R '' 'the significations mentioned above, the opening of the pentagonal cycle of this is carried out with elimination of a formic acid molecule, a 3-nitro o-phenylenediamine of formula III is obtained: ** (See formula) ** having R "and R" '' the aforementioned significance, it is reduced to the corresponding triamine and the latter is condensed with a 2-nitroso 5-dialcohyl-aminophenol of formula V ** (See formula) ** having R and R 'the same signification said, to finally obtain the 3-monoalcohilamino 7-dialcohilamino N-alkyl phenoxazymes-2 sought.
