Versuchsvorschrift
2,6-Dichloro-1,4-benzenediamine (225 g., 1.27 mol) is suspended in methylene chloride (1.3 liters) containing triethylamine (245 mL, 1.7 mol). After the mixture is cooled to 5° C., trichloroacetylchloride (169 mL, 1.5 mol, Aldrich Chemical Co.) is added dropwise with stirring at a rate to maintain 5° C. Upon complete addition, the stirred reaction is allowed to reach room temperature. After 24 hours the mixture is filtered and the collected solid is washed with methylene chloride (700 mL). The filtrate is evaporated to a small volume. A solid is collected and washed with methylene chloride (250 mL) to yield 465 grams of N-(4-amino-3,5-dichlorophenyl)-trichloroacetamide. The product exhibits a mass spectral analysis of m/e+· 320 for C8H5Cl5N2O.
