Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 4102-53-8, name is 4-Iodo-2,6-dimethylaniline, A new synthetic method of this compound is introduced below., 4102-53-8
To a suspension of sodium bicarbonate (126 g, 1500 mmol) and 2,6-dimethylaniline (61.5 mL, 500 mmol) in methanol (700 mL) was added iodine monochloride (1.0 M in dichloromethane, 550 mL, 550 mmol) at room temperature over 1 h. After addition was complete, stirring was continued for 3 h. The reaction was filtered to remove excess sodium bicarbonate and the solvent removed in vacuo. The residue was redissolved in diethyl ether (1.5 L) and treated with hydrochloric acid (2M in ether, 375 mL, 750 mmol). The resulting suspension was stored in the freezer (-15 C.) overnight. The solid was filtered and washed with diethyl ether until it became colorless to give 126.5 g (89%) as a grey-green powder. 1H-NMR (DMSO-d6) delta 2.33 (s, 6H), 7.48 (s, 2H), 9.05 (bs, 3H); 13C-NMR (DMSO-d6) delta 17.4, 91.5, 133.1, 131.2, 136.9.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
