摘要:
The present invention relates to novel triazene compounds, to a process for their preparation, to pharmaceutical compositions comprising them, and to the use thereof in the treatment of cancer diseases in humans. The novel triazene compounds are distinguished, as compared with the known triazene compounds, by improved activity while at the same time having reduced toxicity, that is to say by fewer side-effects.
摘要:
The invention relates to the use of the compound N-(4-fluoro-phenyl)-N-isopropyl-chloroacetamide of the formula (I) ##STR1## which is known, as active compound in selective herbicidal compositions, for example for combating weeds in maize cultures, and to a new process for the preparation of this active compound. The compound (I) is obtained in very high yields by reacting N-isopropyl-4-fluoro-aniline with approximately equimolar amounts of chloroacetyl chloride at temperatures between 20.degree. and 150.degree. C. in the presence of an inert diluent, such as, for example, toluene, without addition of an acid binder.
