The synthesis method of 3 - (diethylamino) carbonyl benzyl alcohol is often viewed according to the idea of "Tiangong Kaiji", and there are several common ways.
First, benzoic acid is used as the starting material. First, benzoic acid and diethylamine are acylated under suitable reaction conditions to produce benzoic acid diacetamide. This process requires careful selection of reaction solvents and catalysts, such as dichloromethane as the solvent, appropriate amount of N, N - dimethylformamide as the catalyst, and the reaction temperature is controlled at 20-30 ° C, which can promote the smooth progress of the reaction. Then, the obtained diacetamide benzoate is reduced under the action of a reducing agent, such as sodium borohydride or lithium aluminum hydride, in a low temperature and anhydrous environment, and finally the target product 3 - (diethylamino) carbonyl benzyl alcohol can be obtained. However, when using lithium aluminum hydride, special attention should be paid to its strong reductive property and severe reactivity in contact with water. The operation must be carried out under strict anhydrous and anaerobic conditions.
Second, benzaldehyde is used as the starting material. First, benzaldehyde and nitromethane react with Henry in the presence of an alkaline catalyst to generate β-nitrobenzene derivatives. Commonly used basic catalysts can be potassium hydroxide or potassium carbonate, which can be heated and refluxed in alcoholic solvents such as ethanol or methanol, and the reaction can proceed smoothly. Subsequently, the β-nitrophenylvinyl derivative and diethylamine are combined in a suitable reaction system, through Michael addition reaction, and then with a suitable reducing agent, such as iron powder and hydrochloric acid system, or catalytic hydrogenation, etc., to reduce the nitro group to the amino group, and then through the nucleophilic substitution reaction in the molecule, the target 3 - (diethylamino) carbonyl benzyl alcohol is closed-loop. This route step is slightly complicated, but the reaction conditions of each step are relatively mild, and the raw material is relatively common and easy to obtain.
Third, benzyl chloride is used as the starting material. Benzyl chloride first undergoes a nucleophilic substitution reaction with diethylamine to generate N, N-diethylbenzyl amine. In this reaction, an appropriate amount of potassium carbonate or sodium carbonate and other bases can be added to the polar aprotic solvent such as acetonitrile to promote the reaction to the right. After that, N, N-diethylbenzylamine reacts with carbonylation reagents such as phosgene or solid phosgene to introduce carbonyl groups to generate 3- (diethylamino) carbonyl benzyl alcohol. However, when using phosgene, due to its highly toxic nature, strict protective measures and exhaust treatment methods need to be taken to ensure the safety of the experiment.

3 - (diethylamino) propyl ether should pay attention to the following key matters when storing and transporting.
In terms of storage, one should choose a cool, dry and well-ventilated place. This substance is quite sensitive to temperature and humidity, and high temperature and humidity can easily cause it to deteriorate. If it is in a high temperature environment, the molecular activity is enhanced, or a chemical reaction is initiated; if the humidity is high, it may absorb moisture and affect the purity. Second, it should be stored separately from oxidants and acids. Because of its active chemical properties, contact with oxidants, or a violent oxidation reaction, or even cause combustion and explosion; when it encounters acids, dangerous chemical reactions may also occur. Third, the storage container must be tightly sealed. To prevent it from volatilizing into the air, one avoids environmental pollution, and the other prevents it from reacting with air components, and at the same time reduces the loss of materials caused by volatilization.
In terms of transportation, first of all, transportation vehicles must meet relevant safety standards. Vehicles should have reliable fire, explosion and leak prevention facilities to deal with various situations that may occur during transportation and avoid accidents. Secondly, the transportation process should ensure that the packaging is in good condition. If the packaging is damaged and the substance leaks, it will not only cause harm to the surrounding environment, but also may cause dangerous reactions due to contact with external substances. Furthermore, transportation personnel need to undergo professional training. They should be familiar with the characteristics of this substance, hazard prevention measures and emergency treatment methods, so that when encountering emergencies during transportation, they can respond quickly and correctly to ensure transportation safety. In short, whether it is storing or transporting 3 - (diethylamino) propyl ether, it is necessary to strictly follow the relevant regulations and operating procedures, and there must be no slack to ensure the safety of people, the environment and property.
