2-ethoxycarbonylamino-5- (4-fluorobenzylamino) nitrobenzene

The synthesis of 2-ethoxycarbonyl amino-5- (4-fluorobenzyl amino) nitrobenzene is an important topic in the field of organic synthesis. To synthesize this compound, the following steps can be followed.

First, a suitable nitrobenzoic acid derivative is used as the starting material. In this raw material, the localization of the nitro group has a great influence on the subsequent reaction. It is first reacted with ethoxyformyl chloride in an alkaline environment, which is created by organic bases such as pyridine or triethylamine. During the reaction, the carbonyl group of ethoxyformyl chloride undergoes nucleophilic substitution with the amino group in the raw material to generate 2-ethoxycarbonyl amino nitrobenzoic acid derivatives. This step requires attention to the control of the proportion of reactants, reaction temperature and time. The temperature is usually controlled between 0-25 ° C and the duration is about several hours to ensure that the reaction is sufficient and there are few side reactions.

React the above product with 4-fluorobenzyl amine. This step should be carried out in a polar solvent, such as N, N-dimethylformamide (DMF). To promote the reaction, an appropriate amount of base, such as potassium carbonate, can be added. The amino group of 4-fluorobenzyl amine undergoes nucleophilic substitution for the ortho-position of the carboxyl group in the derivative of 2-ethoxycarbonyl amino-nitrobenzoic acid, and the target product 2-ethoxycarbonylamino-5- (4-fluorobenzyl amino) nitrobenzene is formed by condensation reaction. The reaction temperature may be slightly higher, about 60-100 ° C, and the reaction time may vary from a few hours to more than ten hours. During this period, the reaction process needs to be monitored by thin-layer chromatography (TLC).

There may be other methods. Nitrobenzene can be nitrified first, and nitro can be introduced precisely, and then ethoxycarbonylamino and 4-fluorobenzyl amino can be introduced in turn. However, this path requires fine control of the reaction conditions. Due to the slight difference in the order and conditions of the multi-step reaction, it is easy to increase the number of by-products and reduce the yield.

During the synthesis process, the reaction products at each step need to be purified, often by column chromatography or recrystallization. Column chromatography is separated according to the difference in the distribution coefficients of the product and the impurities in the stationary and mobile phases; recrystallization is achieved by the different solubility of the product and the impurity at different temperatures. In this way, after multi-step reaction and purification, the target product 2-ethoxycarbonylamino-5 - (4-fluorobenzylamino) nitrobenzene can be obtained.
