Abstract
10,228. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. May 1. Chlorbenzimidazoles.-Relates to the production of amidines of the general formulawhere R represents hydrogen, alkyl, or aryl, and gamma represents hydrogen or chlorine. The amidines derived from as-trichlordiaminobenzene and v-tetrachlordiaminobenzene are particularly useful. The amidines are produced by reducing the o-nitroacylamino. or o-nitroalkylacylamino-derivatives of tri- or tetra-chlorbenzene. A mixture of the amidine and diamino compounds is usually obtained. The diamino compounds with or without previous separation are converted into the amidines by heating either alone or with a dehydrating- agent. The amidines obtained from non-alkylnitroacylamino compounds may be converted into alkylated derivatives isomeric with those obtained from the nitroalkylacylamino compounds, by treating tbeir alkali compounds with an agent such as methyl chloride. The following are suitable parent materials for use in the above process: 1-formyl- or acetyl-amino-2-nitro-3 : 4 : 6-trichlorbenzene (obtained by nitrating formyl-or acetyl-trichloranilide), 1-methylformylamino-2-nitro-3 : 4 : 6-trichlorbenzene, 1-ethylacetylamino-2-nitro-3 : 4 : 6-trichlorbenzene, and 1-ethyl- or benzyl-acetylamino- or benzoylamino-2-nitro 3 : 4 : 5 : 6-tetrachlorbenzene.
