The synthetic route is as follows.
EXAMPLE 8 3-diethylamino-6-methyl-7-(2′,4′,5′-trimethylanilino)fluoran STR17 30 g. of 3-methoxy-6-acetylaminotoluene, 40 g. of 2,4,5-trimethylbromobenzene, 15 g. of potassium carbonate, 1 g. of copper powder and 0.1 g. of iodine were reacted for 75 hours at 220 to 230 C. Then 15 g. of potassium hydroxide and 30 ml. of iso-propylalcohol were added and refluxed for 24 hours. The resultant was poured into 200 ml. of water and precipitate was filtered off, distilled in a vacuum to obtain 35.5 g. (83 percent of theoretical yields) of 4-methoxy-2,2′,4′,5′-tetramethyldiphenylamine as a light brown crystal having a melting point of 87 to 88 C., and boiling point of 165 to 168 C./3 mmHg.
The chemical industry reduces the impact on the environment during synthesis 1-Bromo-2,4,5-trimethylbenzene. I believe this compound will play a more active role in future production and life.
