とが好ましい。2,6-diethyl-4-iodoaniline, which is a compound of the present invention, is 2,6-diethyl-4-iodoaniline. It can be produced by reacting diethylaniline with iodine. The amount of iodine used is 0.8 to 1.
2 equivalents is preferred. This reaction can be carried out at a temperature of 100'C or lower, but from the viewpoint of reaction and operation, a temperature around room temperature is most preferable. Although an inert solvent can be used in this reaction, ether, methylene chloride, chloroform, etc. are particularly preferably used. The reaction may be carried out in a two-phase system of these solvents and water. In addition, in this reaction, the presence of a base allows the desired product 2,6 to be produced in high yield.
- Dinitiru iodoaniline can be obtained. Examples of the base include organic bases such as pyridine and triethylamine, and inorganic bases such as sodium hydrogen carbonate, sodium carbonate, and sodium hydroxide. The amount of these bases is preferably equal to or greater than the amount of 2,6-dinitylaniline.
