The preparation method of DL-3- (1,2-dihydro-2-oxo-quinoline-4-yl) alanine hydrochloride is difficult to find in ancient books, but according to today's chemical technology, the following ways can be found.
First, ethyl 4-chloroacetoacetate and o-aminobenzaldehyde are used as starting materials. In a suitable reaction vessel, the two undergo a condensation reaction under specific catalysts and reaction conditions to form key intermediates. This process requires precise control of temperature, pH and reaction time to ensure that the reaction proceeds in the desired direction. Subsequently, the intermediate is converted into the precursor of the target product through a series of steps such as hydrolysis and acidification. Finally, by reacting with hydrogen chloride gas or hydrochloric acid solution to form a salt, DL-3- (1,2-dihydro-2-oxo-quinoline-4-yl) alanine hydrochloride can be obtained.
Second, 4-methyl-2-oxo-1,2-dihydro-quinoline-3-carboxylic acid can also be used as a raw material. First, specific groups are modified to introduce suitable active groups to enhance its reactivity. Then, the desired molecular structure is constructed by substitution reaction with alanine-related derivatives under the action of specific reagents. After the reaction is completed, the impurities are removed through fine operations such as separation and purification, and finally the compound is prepared by salt-forming reaction.
During the preparation process, the conditions of each step of the reaction need to be strictly controlled. The purity of the reagent used, the reaction temperature, pressure, reaction time and many other factors have a great impact on the purity and yield of the product. And after each step of the reaction is completed, the reaction process needs to be monitored by suitable analysis and testing methods, such as thin-layer chromatography, high-performance liquid chromatography, etc., to ensure the quality of the product.

DL-3- (1,2-dihydro-2-oxo-quinoline-4-yl) alanine hydrochloride, this is a special chemical substance. When storing and using, many matters need to be paid attention to.
Let's talk about storage first. This substance should be stored in a dry, cool and well-ventilated place. Because it may be quite sensitive to humidity, if the environment is humid, moisture can easily interact with it, causing its chemical properties to change and even deteriorate. A cool environment can avoid chemical reactions caused by excessive temperature, which can damage the stability of the substance. Good ventilation can disperse harmful gases that may evaporate in time and keep the storage environment safe.
Furthermore, it should be stored separately from oxidizing agents, acids, alkalis, etc. This substance is chemically active, and contact with the above substances may cause severe chemical reactions, causing serious consequences such as combustion and explosion. Storage containers must also be selected correctly to ensure that they are well sealed. Containers made of glass or specific plastic materials are commonly used to prevent substances from leaking and invading external substances.
As for use. Before use, it is necessary to fully understand its chemical properties and safety data. Experimenters need appropriate protective equipment, such as protective glasses, gloves, and protective clothing. Because it may be irritating, if accidentally touched with the skin or eyes, it will cause injury. The operation should be carried out in a fume hood. If used in an open space, the volatile gas will endanger human health. During use, strictly control the dosage and reaction conditions. Excessive dosage or improper conditions may cause the reaction to go out of control. After use, properly dispose of the remaining substances and waste. According to relevant regulations, do not discard them at will to prevent environmental pollution.
