Now there are 4 - Quinolinepropanoic acid, α - amino - 1, 2 - dihydro - 2 - oxo -, hydrochloride (1:1), to be prepared, the method is as follows.
First take an appropriate amount of 4 - quinolinepropanoic acid derivative, this derivative needs to have a modifiable α position. In a suitable reaction vessel, prepare a suitable organic solvent, such as dichloromethane, N, N - dimethylformamide, etc., depending on the reaction requirements and substrate characteristics. < Br >
The reaction system is cooled to an appropriate low temperature, such as between 0 ° C and -20 ° C, and amination reagents, such as suitable solutions of ammonia gas, amine compounds, etc., are slowly added to make the amination reaction occur at the α position. During the reaction process, the reaction process needs to be closely monitored, and thin layer chromatography (TLC) or other suitable analytical methods can be used. When the amination reaction reaches the desired level, it should be heated to room temperature or moderately heated to make the reaction more complete.
Then, the resulting product is separated and purified. Column chromatography can be used. Silica gel is used as the fixed phase, and a suitable eluent, such as a mixed solvent of petroleum ether and ethyl acetate, can be used to separate the target product according to the polarity difference of the product. < Br >
Then place the purified product in another reaction vessel, add an appropriate amount of hydrogen chloride gas or a suitable solution, such as ethanol hydrochloride solution, under normal temperature or moderate heating conditions, to form a salt, to obtain 4 - Quinolinepropanoic acid, α - amino - 1,2 - dihydro - 2 - oxo -, hydrochloride (1:1). Finally, after crystallization, filtration, drying and other steps, the pure target product can be obtained.

4 - Quinolinepropanoic acid, α - amino - 1, 2 - dihydro - 2 - oxo -, hydrochloride (1:1), is a chemical substance. The safety of this substance is related to many aspects.
