| titleOfInvention | Process for the preparation of N,N-dimethyl-N-(2-bromo-4-methylphenyl)-triazene |
| abstract | A process for the preparation of N,N-dimethyl-N'-(2-bromo-4-methyl-phenyl)-triazene of the formula ##STR1## comprising (a) reacting N-acetyl-p-toluidine of the formula ##STR2## with bromine at a temperature between about 0° and 100° C., to give the intermediate product of the formula ##STR3## (b) reacting the intermediate product with hydrochloric acid by either (i) adding a dilute solution of aqueous hydrochloric acid to the intermediate product in its reaction solution and heating the mixture to a temperature between about 50° and 120° C., or n (ii) precipitating the intermediate product from its reaction solution by mixing with water and filtering off, and without purification or drying heating the precipitate with dilute aqueous hydrochloric acid to a temperature between about 50° and 120° C., thereby to form a solution of 2-bromo-4-methylaniline hydrochloride, (c) reacting the resulting aqueous solution with an alkali metal nitrite at a temperature between about -20° and +30° C., and (d) reacting the product with dimethylamine at a temperature between about 0° and 50° C. |
