Preparation of 2,4-dicyano-3,5-dimethylaniline |
| abstract |
The novel compound 2,4-dicyano-3,5-dimethylaniline is prepared by heating a cyclic compound having the formula ##STR1## and splitting off acetonitrile. The 2,4-dicyano-3,5-dimethylaniline is collected e.g. by sublimation apparatus and is useful as an intermediate in the preparation of dyestuffs e.g. by diazotization and coupling with known coupling components. |
