実験手順
A dinitrobenzene (I) is reacted with, for example, ammonium chloride and iron or with hydrogen gas and palladium on activated carbon in a solvent such as ethanol or toluene and at elevated temperature to give the corresponding aminoaniline (VII). The aminoaniline (VII) is reacted with, for example, thionyl chloride, N-thionyl aniline or sulfur dichloride in a solvent such as toluene or ethanol and at elevated temperature to yield a benzothiadiazole of formula (A'").
