What are the synthesis methods of N- {3- [5- (2-chloro-4-pyrimidinyl) -2- (1,1-diethylethyl) -1,3-thiazole-4-yl] -2-fluorophenyl} -2,6-difluorobenzenesulfonamide

To prepare N - {3 - [5 - (2 - cyanogen - 4 - nitrophenyl) - 2 - (1,1 - diethylethoxy) - 1,3 - dioxypentyl - 4 - yl] - 2 - methoxybenzyl} - 2,6 - dimethoxybenzaldehyde, there are many synthetic methods, and the advantages and disadvantages of each method are different. When carefully selected according to the actual situation.

First, 2,6 - dimethoxybenzoic acid is used as the starting material, esterified, reduced and halogenated to obtain 2,6 - dimethoxyhalobenzyl. The target product can be obtained by coupling 2-cyano-4-nitrobenzaldehyde with 1,2-propanediol under acid catalysis, and then through a series of reactions such as alkylation and hydrolysis, and the above-mentioned halogenated benzyl. The raw materials of this route are common and easy to purchase, and the reaction steps are clear. However, some reaction conditions are harsh, and an anhydrous and anaerobic environment and special catalysts are required, which requires high operation requirements.

Second, starting from 2,6-dimethoxybenzaldehyde, a protective group is first introduced, and the key intermediate is constructed by reacting with halogenated hydrocarbons containing specific substituents. After deprotection, the target is prepared by oxidation, condensation and other reactions. The route of this method is relatively short and the yield is good, but the introduction and removal of protective groups need to be precisely controlled, otherwise the purity and yield of the product will be affected.

Third, the coupling reaction catalyzed by transition metals, such as palladium-catalyzed cross-coupling. With suitable halogenated aromatics, alkenyl halides, etc. as raw materials, under the action of palladium catalysts, ligands and bases, it is synthesized through multi-step coupling reactions. This method has excellent selectivity, mild reaction conditions, and can efficiently construct complex structures. However, the cost of palladium catalysts is high, and the synthesis of partial distributors is complicated, which increases the cost.

When synthesizing this compound, the purity of raw materials, reaction temperature, time, solvent and catalyst dosage will all affect the reaction process and product yield and purity. In actual operation, the reaction conditions should be optimized through experiments, considering factors such as cost and environmental protection, and the most suitable route should be selected to achieve the ideal synthesis effect.

N- {3- [5- (2-chloro-4-pyrimidinyl) -2- (1,1-diethylethyl) -1,3-thiazole-4-yl] -2-fluorophenyl} -2,6-difluorobenzenesulfonamide What are the safety precautions

The structure of this organic compound is complex and contains many special group descriptions. For the safety of such substances, the following points need to be paid attention to:
First, the nature of the group affects the reactivity. Groups such as amine and alkyl groups, if the amine group is active, may easily react with other substances. When storing and using, avoid contact with strong oxidants, strong acids and other substances that can react violently with them to prevent explosion or produce toxic products. For example, amine-containing compounds may form salts in contact with strong acids. If the reaction is violent, it may cause danger.
Second, the spatial structure has an important impact. The spatial arrangement of molecules affects its stability and reaction check point. If there is tension in the spatial structure of the compound, it may make it more reactive and increase instability factors. At this time, it needs to be stored in a low temperature, dry and no catalytic impurities environment to prevent danger caused by structural changes.
Furthermore, consider its volatility and solubility. If it contains volatile groups, it is easy to accumulate in a poorly ventilated environment, and there is a risk of explosion in case of open flames or hot topics. Make sure that the operating environment is well ventilated. If it is easily soluble in water or other common solvents, once it leaks, it will diffuse with the solvent. Emergency treatment plans for the corresponding solvents should be developed in advance.
Finally, its decomposition products may be toxic. When decomposed under high temperature, light or with specific substances, the products may endanger health and the environment. Therefore, when using, it is necessary to strictly control the conditions to avoid decomposition, and at the same time take personal protection, such as wearing gas masks, protective gloves, etc.
