Abstract

The invention relates to a process for the preparation of substituted 3-amninobenzonitriles, which comprises reacting the appropriate substituted 3-aminochlorobenzene with a cyano-donating reagent, and to the compounds thereby produced. The compounds are intermediates, which after further reaction, produce 1,2,3-benzothiadiazole-derivatives having plant immunizing properties.
